Re: [dvd::rip] odd VIDEO_TS (new to this)

Ok this may turn out to be a "duh" moment on my part. I'm 55... I'm entitled to those once in a while I think.... can't remember...

Anyways, I installed libdvdcss2. That helped but I still got an error. So I ran dvdrip from CLI using "sudo dvdrip"
'Lo and behold I got a listing of all the segments on the dvd. I told dvdrip to rip one segment. I now have a VOB file that I can see is the first video clip.

Then I exited dvdrip and used vobcopy again using as sudo... "sudo vobcopy -m"
ZOOOooom.... away it goes... dutifully writing vob files.(and .ifo and .bup files as well.... like... 36 of each... I think it wrote a vob/ifo/bup for each chapter)

Now all of the files created this way are owned by root but I suppose that's easy enough to change if I need to and it appears that libdvdcss2 AND running the programs as root are what made things start working. So then my next question becomes.... is there a way to NOT have to run as root? I don't normally like to do that.

Oh and on a side note... my wife stuck the DVD in her Sony Vaio and it basically hung trying to read it. A whole lotta hourglass. She has WinXP and I'm not sure what software she has on there for playing DVDs but I know she can watch commercially made DVDs (like Shrek).

So I think I'm set for getting the stuff off the DVDs made by the Panasonic dvd recorder in my AV system and can probably start playing around with re-authoring. Would love to get past this run-as-root thing though...

thanks for all the help so far. Feels kinds weird to be a beginner again... but kinda good as well. :)

Okay, that sounds reasonable. You ought not to have any trouble with a
drive like that.

Hmm, the only thing I can think of in that case is a filesystem issue.
DVDs and CDs can have multiple file systems overlaid on top of each
other. They'll have an ISO9660 FS, usually also a "Joliet" file system
for longer file names, and (rarely) a "Rock Ridge" file system, in
which file sytem entries have UNIX style attributes. There are some
others such as UDF as well.

As far as I'm aware, only ISO9660 is required to play DVDs - all the
names are suitably short (max 12 chars I think) and it's a simple
format, so I suspect it gets used by most, if not all hardware DVD
players. The major OSes all support Joliet and various versions of
UDF, and Unix-based OSes also read Rock Ridge.

SO... what if the Joliet file system (or maybe UDF) is corrupted, but
the ISO9660 table is fine? That would explain why it works for
hardware DVD players. Now I guess you just need to disable Joliet
support, although I don't know at what stage you'd need to do it for
dvd::rip, whether it uses the Linux kernel to read the file system, or
one of the userland (lsdvd, vobcopy) apps reads it in from the raw
disc.

I'm no expert on this stuff I'm afraid, so I may be completely wrong here.
