[mythtv-users] Fwd: Mythtv - black screen when trying to watch tv on computer

Hello everyone, new user here. I have set up a Mythtv box running Mandriva
2007 and using a Hauppage PVR 350 capture card. I have my cable line
running directly into the tv input on the card. The card appears to
initialize properly upon boot (see below). I can run cat /dev/video0 >
test.mpg and watch good video/audio in kafffeine. In Mythtv I can connect
to the backend database, run mythfilldatabase and scan channels for Tuner
1. When I try to watch tv or record a program all I get is a black screen.
The watch tv option goes black for three seconds and then exits. I am using
a 20" flat panel monitor that the computer is plugged directly into. I can
see the desktop on the monitor and would like to watch tv on top of kde (not
using tv out). When I pick something out of the channel guide it records
but mythtv says that it doesn't exist in the play back screens. I can see
the video in the /home/recordings directory. Very strange. Has anyone seen
this kind of behavior before? What am I doing wrong? I appreciate any
suggestions.
