I see the same behavior. Also running on 256 (RDRAM) on a P4 2.4 Ghz
with Mandrake 9.1 and PVR-250.
I notice freezes every now and then, which require the application to be
restarted. I also notice that if I leave it on live TV for a while (few
hours maybe) then Myth seems incredibly slow to respond. For instance
if I hit the back button at this point (from live TV) it responds a
couple seconds later, and the screen refreshes very slowly. I don't
have the memory/CPU usage stats but I'll try to gather them soon.
I wasn't sure if this was somehow specific to my particular machine and
setup, therefore I didn't write in to the forum.
I'm building a new machine soon for Myth which will have 512 megs, it'll
be interesting to see how it compares.

Ok, it seems as though I have been able to isolate some memory problems.
Somewhere in the documentation, mythtv or ivtv said it needs atleast 256
MB of RAM. This is a BARE minimum I found out the hard way. Just
running mandrake 9.1 with KDE + the mythfilldatabase I am burning a
whopping 218MB of ram + 14-35% processor time. With my onboard video
enabled (64 MB of shared memory... yuck) I get random pauses during live
TV playback. Its obvious 512 or > is required to run this program
correctly. Btw, I've got a duron 800 (utter crap, I know) with 256 MB
ram/ Hauppauge 250
This may be old news to lots of you, but I thought it was worth sharing.
