[mythtv-users] Busy CPU

I've got a machine running Ubuntu 7.04 Feisty Fawn and I've installed 
the mythtv packages via Synaptic.  A couple minor tweaks were necessary, 
but now it's running, and I'm picking up a few OTA digital stations (I'm 
in the US).

The backend so far looks good.

But the frontend is pegging the CPU... top is sometimes reporting it 
using 100% of the cpu.  The video and audio are usable, but occasional 
and brief video hangs and audio dropouts are experienced.  When I stop 
the frontend and play a recorded program via mplayer, it plays fine.  
Watching a high-def recording with mplayer (off NBC station with network 
programming, should be 1080i I think, and the video quality is great), 
mplayer's using about 80% of the CPU.

Shouldn't my video card be doing more of the work?  See specs:

Intel P4 3.2 GHz (with HT)
Intel D865GBF motherboard
pcHDTV HD-3000
GeForce FX 5200, 256 MB, AGP 8x
300 GB Seagate Barracuda hard drive
Antec Overture II case
Samsung LCD display (sadly 1280x1024 max)
