Choppy picture and sound on DVD playback of movies

[pellets]

Hello

I was not sure on which part of the forum to post this, so i took a chance at this one. Anyways..here goes:

I have the last half year encountered a strange problem i would like to tell you about.
Sometimes, when trying to watch movies i have burned onto empty dvd-r media, i encounter severe choppy picture and sound only a few minutes after having started the movie in my stationary dvdplayer.

It doesnt happen all the time, but once in a while.
And its very annoying when it first happens.
And, whatever i do, i dont manage to fix the problem.

It happens on 5 out of 10 movies I burn, so its annoying enough.

When burning images like *.iso, *.img, "video_Ts" etc of movies i have always used either dvd decrypter or Nero ( newest versions ) of the program.

Before starting a burning-session i always:

disable my antivirus software.
close all other applications.
I use a type of media which i have not had any problem with before.
The two programs i tested with was Dvd Decrypter ( latest version) and Nero Burning Rom ( latest version ).

What annoyes me is that on half the movies i burn there is no problem, but on the other half this problem occurs. And i use the same programs and media on the movies that works as on the movies that doesnt work.

Anyone got any tip on what the problem is ? Please let me know.

Best regards

Hi!

Do these problematic burned DVDs exhibit the same behavior when played on any other standalone DVD players or when played on your PC (Using a DVD software player such as WinDVD, PowerDVD, or VLC - to play "AS DVD", not as individual .VOBs)?

If they don't, your standalone player might benefit from running a DVD/CD cleaning disc on it. Maxell make sone that sells for approximately $10 US...

I'd suggest that when you're burning, make certain to turn off all unnecessary programs (foreground and background, including Internet connections) and burn at 2X or 4X...

Hello :)

Thanx for the reply.

Lets see...

Usually I dont turn of antivirus or my internet connection before starting the burning. But, i always close all other apps, like photoshop, word, iexplorer etc... So I will try to burn with closed internet connection and disabled antivirus tomorrow.

I experience the same problem with choppy sound and picture both trying the standalone as well as the pc-dvdplayer. I have never tried "play as dvd"-function in the dvd-player program though; "Power Dvd"....I dont know if the program as default plays each and every vob or "as dvd".
So I will try this also tomorrow. If there is a function in Power Dvd called something like "Play as dvd".

I have also always used the same media; "Dysan dvd-r". I continued to use it since it worked fine with some movies, even though the problems i described above appears 50% of the time....
So, i will try this also tomorrow.

Tomorrow night i will "publish" my results here. Even if it works or not.
If it doesnt work still, i would appreciate more tips from you :)

Hello again.

Heres what i tried since last time:

I installed Daemon Tools, and mounted the movie-image. ( an iso-file)
I then choosed to watch the movie with Power DVD. I now had no problems watching the movie. The watching went smooth on my pc.
I therefore concluded that the iso-file itself couldnt be the problem.

Then...

I ran a "Dvd Lens Cleaner"-disc on both the dvd-player on my pc, and on my stationarry dvd-player.

After that i did the following:
I closed all apps i had running. ( Word, explorer etc...)
I disabled my antivirusprogram
I opened Windows Task Manager and choose the "processes"-tab. There i closed all unnecessesary processes which were running.

I inserted an empty dvd-r media of the TDK-branch into my dvdburner on the pc.
(Previously i had been trying Dysan, which i have been told lately is crap. Therefore i went to TDK which is know to be a

good brand, in the same category as Verbatim ).

I started the burningprocess by doubleclicking the MDS-file following the *.iso file. Then dvd-decrypter opened ( latest version )
In the burning-options i chose to burn at half the speed. I have a 4x dvd-burner ( Plextor), but i chose to burn at 2x-speed.

After finishing burning im exited ofcourse.
But no ! :-(
The film still has got choppy sound and picture. Wtf ? I now get very depressed, heh

I go into the sound options of the movie. It has got the alternative to choose between Dolby Digital 5.1 ( standard) and DTS 5.1
I ensure that the sound is Dolby Digital and i try both with english subtitles and with no subtitles at all. The problem still occurs.

So, I have still the same annoying problem. Anyone got any other tips ? I would surely appreciate it.
As mentioned earlier this happens on 50 % of all the movies i burn, even if i use the same media all the time.
Untill today i always used Dysan Dvd-R.
But even with TDK, the problems occured again.

Anyone got any more tips? Please give me a reply to this post. Im starting to get neurotic :)

Hello again

I read your answer, and i think i must have deleted you answermessage directly afterwards, because now i cant find your reply anywhere...OMG
Is that even possible? urk

Can you please repost your answer?

I remember that you wrote something about changing the bitrate?
Can u please tell me what program you recommend to do that ?
You also mentioned a special program to to something about a wmf-file?

Could you please repost your answer to me, and also tell me roughly whats the purpose of the two advices you had in your post?

Best regards:

@pellets

Who are you addressing?

I haven't posted anything regarding bitrate or WMF files in my one and only response to you in this thread (and I can't imagine what bitrate or WMF files might have to do with your DVD playback problem)...

@ pellets

you have not yet explained what process you use to back-up your dvd. although it seems most likely burner/media/player related, there may be something in your process (such as excessive bitrate, encoding methods, etc) wish may effect the final result on your standalone player.

in addition, it is not always simply a matter of whether you use well-known media (although it is reccommended as a mighty fine place to start) but also a question of media compatibility.

Hmm..Hello once again... :(

Now i used dvd decrypter.
I chose the Mode-IFO setting.
Thenafter I chose to, in the stream processing tab, to "enable" streamprocessing for all of the choices mentioned in that tab. Both for video, audio and subtitle.
Then I started the streaming.
But, after having finished, and checking the output-folder.
I cant find any ac3-file, or any soundfile for that matter, anywhere there.

i end up with the following:
1 exemplar of Stream Information.txt
1 ex VTS_06_0.IFO
1 ex VTS_06_1.VOB
1 ex VTS_06_2 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V

1ex VTS_06_3 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V
VTS_06_4 - 0xE0 - Video - MPEG-2 - 720x480 (NTSC) - 16~9 - Letterboxed.M2V

But, no ac3-file.
When inside the Dvd Encrypter program i surely see that there is a m2v and a ac3-file, but after finished processing i cant find the ac3-file, but instead the files mentioned above.

There is a file there called Streamer information.txt, and this file says the following:
"
0x20 - Subtitle - [SubPicture 01: Wide/Letterbox] / LBA: 20459 / PTS: 00:01:12.338 / Delay: 72105ms
0x21 - Subtitle - [SubPicture 02: Wide/Letterbox] / LBA: 20458 / PTS: 00:01:12.338 / Delay: 72105ms
0x80 - Audio - AC3 / 6ch / 48kHz / DRC / English / LBA: 6 / PTS: 00:00:00.233 / Delay: 0ms
0x89 - Audio - DTS / 6ch / 48kHz / DRC / English / LBA: 5 / PTS: 00:00:00.233 / Delay: 0ms
0xE0 - Video - MPEG-2 / 720x480 (NTSC) / 16:9 / Letterboxed / LBA: 1 / PTS: 00:00:00.233 / Delay: 0ms
"
At least, there is the soundfile menitoned.....
Anyways..thats one problem.

I install ( after having bought) tmpgenc. There it occures the framrate is 8500 kb per sec.
You said it shouldnt be ove 8000 kb / sec for television? So, i assume the problem lies here?
Anyways..I cant find any option in tmpgenc for me to reduce the framerate at all. Is there another program you could recommend for me to accomplish this task?

Will surely appreciate any help.

@pellets

sorry mate but you are confusing the hell out of us here .... it seems you sre mixing up the responses from the two different forums you hae opened threads in ... please try to maintain focus on each thread, so we dont feel like we are in an M C Escher building when trying to read your posts :p

first step:
please check your player/burner/media compatability in the links i provided above ...
then experiment with the media by taking a DVD-5 you own, creating an .iso image with dvd-decrypter, then burning this image onto a compatable blank, using dvd-decrypter, then test this in your standalone.

hopefully this will at least rule out media, for the time being.

second step:
please explain the method you have used to process the ORIGINAL DVD to fit ontp a blank dvd-5.
if these are movies you do not own, then please read this before proceeding further:ATTENTION: Read this before posting! Especially on downloaded movies, or movies you do not own! (http://forum.doom9.org/announcement.php?f=6)

finally, when using dvd decrypter in stream processing mode, it will only demux the stream you have highlighted (as apposed to selected). so, if you want to demux the .ac3 stream you will have to highlight it.

Hello :)

Thanx for the reply.
Yes, im indeed mixing up the answers from two different forums.
Im sorry for that :) To many browserwindows up at the same time.

Back to your answer:
Its not a downloaded movie, just a movie i made an iso-file-backupup of, some time ago.
It seems i did a not so good job making the iso-image. Because when i burn the iso-image onto an emtpy dvd-r, and plays the movie on my standalone dvd-player i encountered choppy sound and picture.
Someone told me this could be due to the bitrate being higher than 8500, since on a movie it shouldnt be larger than 8000.
I therefore have been looking all around to find a program that can let me set the bitrate myself, when reauthoring the dvd..or what you might call the process.
Someone told me that i first should use dvd decrypter to deflux the whole thing, to make one ac3 and one m2v file.
This i think is a bit confusing, since there are several vob-files on the disc, so what vob shoudl i choose in dvd-decrypter for the deflux-process so that i get the "right one" of the m2v-files? Because there are several vob-files on the dvd, naturally enough.
So, thats one question.

Someone also told me that i thereafter could use tmpgenc to manaully set the wanted bitrate of the movies, but i cant find such a choice in tmpgenc at all. If you could advice me on how to do this, i would aprpeciate it.

you still havent explained how you processed the dvd in the first place!
...unless the original was only single layer?

stream processing in dvd decrypter is via pgc. to simplify things you may want to try pgcdemux by jsoto:

I had pretty well the same problem. I bashed my head against the wall, cursed every disk maker for making crappy DVDs. Startedd to put my pennies together to buy a new burner as obvisouly mine has screwed up.

Out of final desparation I reduced my burn speed to 1 in the software packages that I use. I also made sure I had turned on SAO in the CopyToDvd settings, as I use this driver most of the time through Windows Explorer. This seemed to solve my problems.

I haven't had to frisby any into the garbage now for several months.
