I have MythTV running, but what I would really like to do is watch
TV in a window on my desktop.

There are several apps out there but none seem to work with my Hauppauge
PVR-250. I've tried xawtv, TV Time (which is excellent), and Zapping TV
viewer.

Does anyone know whether any of these apps *should* work with my card
(i.e. I've got something mis-configured), or if there is another TV app I
could try?

Thanks,

-Paul
