[MPlayer-users] Video stream is mandatory! recording from dvb device

[Brian J. Murrell]

I'm trying to use mencoder to record from either my Hauppage HVR-950q
or HVR-1600 both using clearqam cable.  The cable signal and devices
are working as dvb-apps' "gnutv" can successfully record from them.

When I try to record using mencoder I get:

$ mencoder -v dvb://120 -o test.mpg -oac copy -ovc copy -dvbin ca
