[MPlayer-users] working mencoder now causing floating point exception

Yeah, that helped -- Thanks.
Unfortunately, I'm still getting a floating point exception.
I've tracked it down to lameopts "cbr"; "vbr" and "abr" work OK.
I changed the previous command line to encode only 1 second, removed the 
"br" specification, and removed the video encoding portion to reduce output:
mencoder tv:// -tv 
driver=v4l:width=640:height=480:norm=NTSC:chanlist=us-cable:channel=8:device=/dev/video0  
-ovc frameno -oac mp3lame -lameopts cbr  -endpos 1 -o vv.avi -v

And get the following output:
