 I found an old Medion MD5044 tv-tuner card which I popped into my mythtv as

1.1 GHz doesn't sound like very much to be doing software encoding of
the TV signal, and simultaneously decoding it back. If you're watching
"live TV" this is what it's doing. Run "top" to see what your CPU
usage is - there's probably no idle CPU and it can't cope.

If you get a PVR350 you'll only be using your CPU for playback so it
may not be a problem then.

Have a look at http://www.mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1 to
see hardware requirements for MythTV.
