What's the difference? |
|
|
I've always created DVD's by using DVD-Lab to create a hard-drive
directory (VIDEO_TS & AUDIO_TS directories), and then using Pinnacle
InstantCopy to use these directories as source (specifically the
VIDEO_TS.IFO file) to burn to DVD.
I decided to try and just copy the VIDEO_TS & AUDIO_TS directory
directly to a disk using Roxio burner software, since it takes half
the time over InstantCopy. The resultant disk plays fine using
PowerDVD on my PC, but for some reason doesn't play on my 'set-top'
DVD player.
I compared the 2 disks - they have the exact same set of files, but I
noticed that the VOB files are of slightly different sizes (although I
think the total number of bytes across the set of VOBs is the same -
looks like InstantCopy chopped the VOB's at a different place).
So why is my set-top DVD player unhappy with this disk? What's the
magic that InstantCopy is doing to the files/file structure to appease
the player?

set-top players require UDF descriptors that are not written when you burn
the disc as a DVD-ROM. I do not know about Roxio, but Nero has a DVD-Video
project that does just that - burns the disc, including UDF descriptors.
Something like that may exist in Roxio, too. |

Did you ensure that the isk format was UDF?
If it wasn't then the Pc wouldn't care but set top players will.

Also.......Don't overlook the possibility that the 2 different burner
software products (InstantCopy versus Roxio) may and probably do use
different burner engines with different drivers. Therefore the actual
recorded disks may look very different to the playback machine even though
the file formats and disk layout are otherwise identical.
