[MEncoder-users] improve saa7134 TV-card stream recording

[ivo.linux]

Dear Friends

I am trying to record saa7134 TV-card stream using mencoder. I used the 
following .
*********

mencoder tv:// -tv 
driver=v4l2:device=/dev/video0:width=640:height=480:norm=PAL:alsa:adevice=hw.0 
-ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1500:vhq -vf pp=lb -oac 
mp3lame -lameopts br=128:cbr:mode=0 -o inter-roma.avi
*********

I obtained a poor quality file. In detail: the video flow is 
discontinued (stop and go) and audio is not synchronized with the video

This is a cutting of my terminal

*********
22 duplicate frame(s)!

Pos: 32.2s 615f ( 0%) 19.48fps Trem: 0min 0mb A-V:0.000 [391:127]

video buffer full - dropping frame

Thanks in advance for any help
