Matrox G550, two monitors, tvtime

[James Kaufman]

I have two monitors being fed by one Matrox G550 video card. I have a Pinnacle
TV card as well. I can run tvtime on the first monitor and all is well. If I
try to run it on the second montor, I see the error message:

xvoutput: No XVIDEO port found which supports YUY2 images.

Any thoughts? Pointers?

Thanks.
