[MPlayer-users] tv mode a/v sync problems (again)

hi!

I'm here still trying to get a good a/v sync with the v4l capture
mode.

i've asked to several people, and someone on the mplayer channel says
it's possible to use the btaudio device to capture the audio with this
command line:

mplayer -vo xv -fs -tv\
on:driver=v4l:device=/dev/video:input=0:norm=PAL:channel=E2:\
chanlist=europe-west:width=640:height=480:outfmt=yuy2:\
adevice=/dev/dsp2:amode=1:audiorate=32000:forcechan=2 -nocache

but it doesn't work for me (no audio)

so i'm trying with the loopback cable, and i have a very bad a/v sync,
is there a way to force a sync in this situation ? i mean, using the
loopback cable is there a way to control the audio syncronization ?

my settings are:

vo = xv
ao = oss (tried also with alsa9)
cpu = Athlon 2200 xp
1Gb ram
capturing video without any postprocessing results in 1% cpu usage,
while capturing video with `-vop pp=lb' results in a 40% usage.

any suggestion ?
thanks again !
