DVD Architect 1.0b off standard ?

Hi,

I tried to REGAIN a mpg-test-file from the DVD-disk and failed.


I use smartripper - the most common tool for that purpose.
The file which smartripper extracted from the DVD was 20% bigger than the original Test-mpg. It could not be played, the format could not be identified.


When I authored the DVD-disk with the ULEAD-DVD-plug in everything went smoothly. Smartripper regained the mpg-file from the disk which had exactly the size of the original Test file and was identified as a DVD-mpg-file.

To allow regaining the original mpg-file is something I expect from an
authoring program. Sometimes I rearrange my own DVDs.

just tried to use SmartRipper 2.41 to extract streams out of a DVD-A created
DVD-R.
It extracted all files fine (same size, play fine) except the ones that are 1GB in size
(1048576 KB)
They can not be read by SmartRipper.
Rips fine from other DVD's
Will test further...

okay, here is a possible problem.
I tried to use Nero (5.5.10.28) to burn
the set of video_ts files that DVD-A prepared.

I get an error that I have seen before trying to
use Nero to burn DVD-A created files, but it
occurred sproadically, so I could never track it down.

"File size is not a multiple of a logical block size (2 KB)"

Hmm, I prepare another set of files using DVD-A,
this time there are no tracks that are over 1GB in size,
so therefore DVD-A does not split into
1,073,741,824 byte (2^30) files.
Nero does not complain now, and SmartRipper can
extract all files fine, from a DVD-R created by Nero
or DVD-A.

So, for now, I guess if you want to extract all files
cleanly with SmartRipper from a DVD-A prepared/burned,
keep the files under a 1G.

Oddly, all the store bought DVD's I have tried so far, have
VOB files that are not exactly 1GB, one DVD had all files
that were 1048574KB, 2KB less than 1GB (2^30)

Please, others corroborate/dispel these findings using DVD-A, Nero,
and SmartRipper.

What could be special about the vob file that is exactly 1GB?

DVD-A 1.0c
Nero 5.5.10.28
