SVCD Playing problems.

[DMJ06]

The DVD2SVCD program works fine, but not for every DVD/SVCD Player.
Players (SVCD compatible), I have tested are interupting (freezing) video after some time of playing, why ?
Does my tested burning speed (8x) with Nero 5.5.9.4 still influence the reliability of the result ?
I heard that only a very low burning speed(1x)gives good reliability with SVCD's ??

[spinspan]

that is not true.
I burn my svcd's (i have 260) at 32x on NoName CD-R's.
Try to test your movies on another player.

Burn speed _can_ be a factor, but it isn't always. It totally depends on the media, drive, and other factors.

Post your logfile so we can try and determine the problem.

Yeah it can matter on burn speed depending on your setup, but another thing we should remember is that you should also try the way we have found is the best and safest way to burn the cue/bin files here is a link http://forum.doom9.org/showthread.php?s=&threadid=21859 take a look at Q61:

There are so many things that can cause your problem.

If it's just freezing and not showing signs of blockiness or green blocks I doubt it's a burn speed issue.

Try lowering your bitrate and do some test encodes using CDRW discs and a couple of chapters using CBR to make sure the bitrate is always at it's highest. Try at different rates. It could be that the video you are playing doesn't hit it high bitrate point until the place you are having problems. Not every DVD player can handle the same bitrates.

If that doesn't solve your problem post your logfile using cut and paste not attach.

Im not sure if this is your problem, but without any logfile, you make it hard to determine. When my audio bitrate is too high, ive had the same problems, freezing. Try your audio b/r at 128 (default) and see if that helps, if not, like previous posters have said before, its most likely your media or your player as the culprit to your problems.

Forgot to ask, are you downsampling your audio, or leaving it at 48? Try both, maybe it will help.

...also, make sure you don't put any cd labels on the cd, as when the cd heats up after some time of continouous playing,(about 35-40 mins) it might be getting warped (not permanently, but enough for the laser beam to get "lost"), so freezes would occur on an otherwise perfectly burned disc. If freezes happen on a cold disc, then see comments above. Low burning speeds is a must, but IMHO, 1x is too low. 4x is generally considered the golden rule here.

about the burning speeds, i would try to burn fast first and if it gives you problems burn slower...ive never burned anything slower than 24x since i got my new burner about 1.5 years ago and ive never had a single problem that could be fixed by burning at slower speeds.

Thanks for all your help so far.

Continuing story.
The freezing problem exists in most of my SVCD CD's. Because I tested the CD's only at the beginning and not after about 20min. playtime, I found the problem very recently.
I do not have the raw material available anymore (DVD, Log file etc.), but I have done some additional testing myself.
The "bad" CD with SVCD information on it runs bad on my PC DVD player with WinDVD4 as well (stuttering). I have made an image of the "bad" CD with CloneCD and mounted on my DEAMON virtual CD, what happens ? It's running fine now, no problems on the PC !
I have burned the image on a CD-RW at 4x and this CD-RW is running fine on my PC DVD player now, no stuttering anymore. Now on the standalone DVD player, no problem any more !!!! Conclusion: The Data on the "bad" CD was still good !

Can anybody give me an explanation ?

Of course I have to continue to investigate the problem. First at higher burn speed, second on different CD-R's.
The CD-R's I'am using so far are of high quality (Nashua 800MB ,
1-32x).

When I use DVD2SVCD I don't play with the settings for bitrate and audiorate (128 / 44.1). I have set the CD size in the bitrate Tab all at 800MB that is all. Any better suggestion ?

[markrb]

I can only throw out some suggestions.

Some DVD players, mostly Sony's, have issue with CDR media and will only work with CDRW media. Some DVD players will only work with certain colors of media (ie. Blue, silver or green). Try a different color media for your CDR.
Why there also seems to be a problem on your PC I cannot say.

128 bit audio has often been found to cause problems on standalone players. Try rasing to at least 160 if not 192. You will like the better quality of audio better anyway.

Thanks for the Audio setting advice.
I have done some more burning now. On the same CD-R (Nashua) burn speed 4x, no problem anymore. I still have to try 8x burn speed.
I do have an idea what may have caused the problem, the CD Label !
So far every CD got a printed label. One DVD makes 2 CD's and I put them both in the same Jewel case. The sensitive layer of the CD was in touch with the printed label of the other CD for some time. So, may be, that the ink on the label (chemicals) has done something with the CD-R ??

[Arianos]

That would only make the first CD problematic, not the second. Re-burning the CDs and having no problems afterwards, suggests a high burning speed the first time, or maybe some (compensated) buffer underruns that although are ok for data CDs, are murder for audio CDs or as in our case SVCDs.
BTW, there are 2 and 3 CDs Jewel cases, so you can safely store your SVCDs.

Yeah i was leaning towards burning issue myself, plus if you are having problems guys with your disks playing specially if they are studdering on your pc, then i could safely say try burning with the method we laid out using "deamon tools" loading the cue/bin file in that then burning with nero.
