I was curious about this so I ran some tests.
I dont have dvd tools so I just get an ISO using linux of an unencrypted
source DVD-R.
dd if=/dev/dvd of=img.iso
Test 1
tested playing the filesystem image file like in your example
(gathered from your command -v line output)
mplayer img.iso
fails as the video is playing back wrong but there is sound from liba52
ac3 decoder.
(it is out of sync with video)
Test 2
alternate attempt (mount image file)
as root
1) mount filesystem
mount -t iso9660 -o loop img.iso /mnt
(loopback and iso9660 filesystem support must be compiled in your kernel)
as normal user
2)
mplayer -dvd-device /mnt dvd://1
(see mplayer manpage for more options for DVD playback etc )
plays better - video okay but Machine is too slow to keep up and audio
is out of sync.
Further tests
I tried several suggested different options
like adding -cache 8192 to 65535
and new -ao or -vo (audio and video outputs)
plus tried using CVS build versus 1.0pre3
no luck audio still out of sync.
by the way playing the DVD-R directly from the DVD device /dev/dvd
also fails with same audio issues.
just a note VideoLan Client - vlc 0.7.1-2 which I just also had installed
vlc img.iso
seemed to work quite well in this test audio was in sync and video played
back looking fine.
or vlc dvd:/dev/dvd at 1
Good luck.
