[MPlayer-users] Question about .ifo and .vro files on a Hitachi dvd-ram camcorder

[Jason Hollinden]

Hi,

I have a Hitachi DZMV230A camcorder, which records on 70mm dvd-r and
double sided dvd-ram disks.  What I'm trying to accomplish is to make svcds 
of the dvd-ram disks, which stores in a .vro file instead of a .vob.  The
reason for this, from what I've read, is that .vob files can only be
1G, where this .vro file contains all the tracks in a single file.  The
.ifo file keeps track of where the tracks start/stop in the .vro file.

For a short while I had checked my soul at the door an ran XP, and if I
just renamed the .vro file to a .vob, I was able to make an svcd, but
there wasn't any track info, just one solid movie.  I've only been able
to find one commercial program that reads the .vro files correctly, but
it looks to be playback only.

Now that I'm done rambling, my question is can mplayer (or I guess
libdvdread) decifer these .ifo/.vro files?  Google doesn't turn up much
for vro files, except other "hey, what can I do" posts.  I can't upload 
anything at the moment, as I'm still figuring out how to make the thing 
work over USB at the moment.  Once I got that working, I can record a
short time, with several starts and stops (that's how it does tracks,
each time the record is stopped/started) if anyone wants to take a look.

Thanks....

   In biology -- and the economy -- simple rules produce complex behaviors.
   That's "simple" rules.

   The Lord's Prayer is 66 words, the Gettysburg Address is 286 words,
   there are 1,322 words in the Declaration of Independence, but government
   regulations on the sale of cabbage total 26,911 words.

   That's "cabbage." Cole slaw, we presume, is more complicated.
