[mythtv-users] HD Playback (on a SD tv)

Okay, I need some help getting my playback settings working. I can't  
seem to find settings that work.

I got the recording side of things working (with the HD cards and  
such), but now I can't get the frontend to play them. It stutters a  
bunch. I can play the files from mplayer fine though.

Setup:

Master Backend:
P4 2.4ghz
1gig ram
2x Pinnacle HDTV pci cards
multiple drives.

Slave Backend/Frontend
P4 2.8HT
1gig Ram
1x Hauppage WinTV-Go Plus (bt878) pci card
Nvidia GeForce4 Mx 4000 128mb

I have a NFS share to /mnt/myth (my recordings dir) setup, but  
currently myth isn't aware of it.

When I play the files through the frontend (and I've tried ALL KINDS  
of playback profiles) they're all stuttery and at first I thought it  
was network lag, but when I run mplayer from the command line, it  
plays them just fine. Anyone wanna give me some pointers? The roomies  
are joking about getting a dish DVR as a backup for when I upgrade.  
We haven't had a working myth system in a week... and my bt878 card  
STILL has audio sync issues... but I think that might be resolved  
with a new kernel, the pinnacle driver problems were resolved by  
upgrading from 2.6.22 to 2.6.24 (had to compile it myself though).
