Thanks much! Command line vlc works now, but vlc.app is really touchy
with regards to the open file dialog. More specifically, when I click on
a file to open, the app frequently quits, sometimes following the system
spinning disk cursor. I'm guessing this is related to some code that
identifies if a file is OK for the app to open or not, since it has died
every time selecting the unencrypted vob file to open, dies if I
accidentally click on (but not open) a tiff file, for example, and
sometimes when i click on and try to open a supported MPEG1 file. And,
of course, thanks to something (maybe the OS?) remembering which file I
was trying to open last in that application, any subsequent attempts

OK... here's the info I have, first the kernel panic text (hand copied
from the screen of the crashed box. I double checked it all but it's
possible I may have mis-typed something):
Unresolved kernel trap(cpu 0): 0x300 Data access DSISR=0x40000000
DAR=0x0e893138 PC=0x12743c88, MSR=0x00009030
generating stack backtrace prior to panic:
backtrace: 0x12743c80 0x12743c80 0x127483b8 0x0024adb8 0x151a5b98
0x000c2cc8 0x000bfb70 0x001a621c 0x0009d1e4 0x00099440 0x00000268
kernel modules in backtrace: DVDioctl(1.0.0d1)@0x151a4000
kernel module dependencies:
Memory access exception (1,0,0)
What I did that caused the panic:
vlc run as: ./vlc dvd:/dev/dvd
Sorry I didn't run it with -vvvv :-(
The DVD in the drive was The Matrix (US release)
vlc build 0.2.70, DVDioctl kernel module from that release loaded, with
source mods to enable dangerous io following instructions I found in the
list archives (either vlc-devel or vlc, I forget) from March(?).
intf: interface initialized
vout: video display initialized (720x576, 32/32 bpp)
vout: YUV acceleration unavailable!
I connected with gdb (the remote debugger) from another machine while
that machine was still panic'd. Since I don't really have any experience
with gdb, I dug around in the help file but this is all the info I could
really get it to show (I believe this is a stack backtrace... it should
match the kernel panic output above):

Neither... I've been testing with an unencrypted VOB file obtained using
a MacOS 9 app called DVDExtractor that reads a DVD, decrypts a vob file,
and saves it to disk (necessary since I don't own any unencrypted DVDs).
I've been getting around 18-22 fps playing that VOB file off my hard
drive using the command line vlc program.
Hope that helps.
