I tried with 1 through 4 with pretty much the same result.

weird, it always worked with just --warning. ok, I now tried this:

./vlc --warning 1 --input dvd /dev/dvd

result: it runs to the "locking module 'yuvmmx'", then does something
for a looooong time. unfortunately the "something" doesn't include DVD
playback, even though the DVD light is flashing, so the disc is being
accessed as it seems. I also see about 900 bi in vmstat and the CPU is
50-60 % utilized. it's doing something.

ah! after about 2 minutes or so, it stops. no DVD access anymore, no
bi, but 100% CPU load.

this was face/off, an unencrypted DVD that starts with a menu. I'll now
try a crypted DVD that starts right with the movie.

one more news: when I hit ctrl+c, it prints some more info:

module: locking module `dvd'

the DVD that starts right with the movie - WORKS! it's using around 80%
CPU, occasionally more (up to all of it, this is an athlon 550) and picture 
quality appears lower than I'm used to, but that may well be a wrong 
impression (I usually don't view the DVDs on the computer monitor - I have 
a beamer and a dedicated video room)

more things that you may or may not know already:

moving the window while it's playing is a guarantee for 100% CPU useage
and skipped frames. sound volume is lower than other sound sources. it
also has the same playback problems that my windos player has - this
DVD has a scene where the camera pans past a large array of candles,
which seems to be too much for the mpeg decoding.

switching to hardware acceleration reduces the CPU load, but the
playback loses sync between audio and video. however, vlc seems to have
a great feature that I haven't yet seen in any windos player - it
catches up, and gets back in sync. wow!
