[MPlayer-users] horizontal lines in tv capture

I'm getting horizontal lines in TV capture. 

I'm using mplayer 0.90, built from source, although it identifies itself
as 0.9rc5.

[yan at poseidon yan]$ mencoder -v

MEncoder 0.90rc5-3.2 (C) 2000-2003 Arpad Gereoffy (see DOCS)

CPU: Advanced Micro Devices Athlon 4 PM Palomino/Athlon MP

Detected cache-line size is 64 bytes
CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0

My mencoder line:

mencoder -tv on:driver=v4l:input=1:width=720:height=576:norm=PAL -vop
scale=320:240,crop=704:560:8:8 -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=900:vhq:keyint=100 -oac mp3lame -lameopts
cbr:mode=3:br=64 -o krtek7.avi

There are horizontal lines that come and go.  They appear to be
artifacts of the capture/compression process.

If I capture at lower resolutions - 320x240 - they don't appear (or at
least are not noticeable.)

I've tried -vop pp=hb:a/vb:a/ci,scale=320:240,crop=704:560:8:8 with no

Any ideas?
