useless double layer discs, why?

[johnhamler1]

whats the point to burn movies on DL discs when it is not working on my dvd player (philips 3020).

I got these disc when in texas, and bought them from walmart (3 discs for 15$) , verbatim .

did a copy of K.kong, and I have been deceived when my dvd player said "unknown disc".

please,give me some good news!!!

Hi!

1) Does the burned DVD play on your PC?

2) Did you use "bitsetting" (or does your burner do this automatically for DL media?)?

3) Have you tried playing your burned DVD on any other standalone DVD players?

whats the point to burn movies on DL discs when it is not working on my dvd player (philips 3020).What's the point of those discs, because they don't work on your player? Well, I suppose we can stop the production of those discs now, can't we. What's the point in producing them if they don't work on your player? :rolleyes:

Seriously though:
1. Have you tried both DVD-DL and DVD+DL?
2. Is the layer break at the correct place?

Is the layer break at the correct place?Indeed...

Given an single or dual-layered blank recordable DVD has less storage capacity than an "store-bought" DVD, it should come as no surprise that the layer change trigger will be in the wrong place :scared:

Some players have bugs in the firmware and cannot play home made dual layers.

@ SeeMoreDigital:

i thought they had the same capacity as OTP discs... i haven't had to shrink anything to burn to one of these so far, but it's rare that a disc is so full that it needs to go PTP.

PTP is more trouble than it's worth anyway... replicators stuff them up too often, and the layer break pause is LONG due to the laser having to move all the way back to the beginning of the disc.

but DVD+R DL discs should be burnable perfectly if one uses PGCedit and imgburn to set the layer break to a good place.

i think setarip_old has it with bitsetting. if the drive isn't doing it, chances are the player will just ignore the disc. DVD+R DL should be bit-set to DVD-ROM booktype.

@ johnhamler1:

figure out how your drive is burning the disc, use PCGedit and blutach's DL burning method, and don't use nero unless you're burning DVD-5 or putting data on a disc.

here my mistake, I burned the image as if it was a file and not an image.

so my standalone palyer didnt detect the Video TS file (but detect only the ISO file)and gave me a "unknow disc".

buned again a movie, and now it plays fine in my 3 st alone player...

1 remark, the laser go from inside to outside, change layer 1 to 2 and back from outside to inside the disc.this is what I have read somwhere!!!


long life to DL...

thank you 4 ur replies.

here my mistake, I burned the image as if it was a file and not an image.It's a good thing you didn't make that mistake the first time you tried to burn a single-layered DVD - You would have posted that it's impossible to burn ANY DVDs ;>}

Glad to hear you figured it out!

for burnt DVD DL discs, this is the only way. it's called "outer track path" or "OTP". doing it this way means layer 1 can never be larger than layer 0, which reduces the amount you can fit on a disc (unless you have a non-seamless flagged chapter in exactly the right place).

pressed discs also have the option to be "PTP", or parallel track path. this means the disc plays from inside to out on layer 0, then moves right back to the start, switches layers, then plays from the inside out again. this means layer 0 can be bigger, but the layer break pause will be much longer. it also increases the risk of replicator error and playback problems. but if you've got a disc that you absolutely can't shave any megs off, it's often the only choice. currently this type of disc cannot be burnt. i'm not even sure the DVD+R DL standard allows it.

[johnhamler1]

is there a free easy software where I can check where my change of layer is. I guess it is between chapter in my movie?

how can I know the change of layer will not change and be in the movie?cutting sound and picture!

for a DL burner'wanabe, what do you suggest me?

You can use PgcEdit to burn your DVD-Video files to a DL-DVD. You can set the layer break at any cell that is suitable for the layer break, and, by default, the original cell is selected.
However, PgcEdit cannot modify the files in an ISO image. To use PgcEdit, you must rip the DVD in file mode.

If you want only to be sure the layer break is at the right place, you should mount the ISO image with a program like Daemon Tools, and open it in PgcEdit. Then, open the PGC Editor by double-clicking on the main title PGC, and locate the cell with the layer break flag set. Don't use the burn function, as it will fail with read-only files.

Note that if you rip the DVD with DVD Decrypter in ISO mode, and burn it with ImgBurn, the layer break position will not be modified.
Anyway, do not burn the DVD with Nero, as it doesn't respect the layer break position, and imposes its own position!
Also, use ONLY Double Layer DVD+Rs! The layer break CANNOT be placed at the right position with Dual Layer DVD-Rs (unless you use PgcEdit and ImgBurn, and you accept to change the position, but even in this case, it's not recommended!)

...and even PGCedit is no match for a PTP disc as i discovered the other day with my Invader Zim discs. that was a waste of a disc :( ended up (educatedly) guessing a layer break, and the resulting burn decoded several blocks from the wrong angle every ~2 seconds on an I-frame.

funny thing is i hadn't a clue that those discs were even PTP, but it makes sense as the only sane layer break is well before the first allowable break for an OTP disc.

What's the relation between PTP/OPT, burning, and angles and I frames? :confused:
