I have tried that. I get one encoder that works and the other encoder simply
gives a blank screen. After a few moments the live tv screen goes back to
the watch tv menu.

The two cards are set up as follows:

video: /dev/video0
VBI:   /dev/vbi0
audio: /dev/dsp
default input: S-Video0

video: /dev/video1
VBI:   /dev/vbi1
audio: /dev/dsp1
default input: S-Video0

The only funny thing I notice is there is not a dsp0,dsp1,dsp2, etc like the
rest of the devices. Could this be the problem?
