I have a DVD of a live performance I was involved in and wish to make a backup copy. I own a copy of DVDFab 5 and even upgraded to DVDFab 6, however only unlocking the DVD to DVD with my DVDFab 5 license. Regardless of whichever software I use, the end result is the same.
The DVD is not encrypted with anything. The only strange thing about it, which I’ve never seen before is that despite the fact that is your standard SL Verbatim DVDR (4.7gb), if you look onto the contents of the DVD itself, it thinks VIDEO_TS is ~366gb in size. Quite obviously it is impossible to have something that large when the limitation is 4.7gb. I’ve tried using Windows, MAC, Linux and FreeBSD (I’ve proficiencies in all of them).
Pretty much any DVD software I use will open VTS_01_0.VOB and VTS_01_1.VOB, then fail out with I/O issues. It seems the next part of the disk that contains any real content isn’t until VOB 33, otherwise it hangs any other software.
Specifically to DVDFab, it doesn’t fail. It just reads the beginning of the disk, then finishes as expected, however, it is only the first 26s of the disk and doesn’t contain the actual content of the disk itself.
If you view the contents of the disk, there are files going from VTS_01_0.VOB VTS_01_1.VOB to VTS_99_0.VOB VTS_99_1.VOB with occasionally throwing in a VTS_##_2.VOB on certain titles.
The sizes also follow a pattern, for example:
VTS_03_0.IFO 38 KB
VTS_03_0.VOB 114 KB
VTS_03_1.VOB 1,048,574 KB
VTS_03_2.VOB 240,018 KB
However, if you’re familiar with *nix, running
file against those VOB says it can’t tell what kind of data it is (meaning it’s likely fake data), which is the case for most of the VOBs.
The only program that showed anything different was CloneDVD. Titleset 34 (which corresponds to VOB 33)was the right size while the others weren’t. It did make an iso of the DVD, of the right size, but the menu’s don’t work in the sense that they loop on themselves. I click play, it starts back over at the menu’s and that is the closest I’ve gotten. I can manually play the VOB when I explore the disk, but that’s not good enough.
The disk itself is not damage and plays fine in both commercial players and computers of varying OS’s. Has anyone heard of this sort of file trickery before and if so, how do I get it to play nice, specifically with DVDFab?
