The default recording resolutions and bitrates for MythTV are a bit 
high.  Try lowering the resolution to something like 352x480 and record 
using MPEG-4 at a bitrate of 2200 (1 GB / hr).  You should find that it 
works much better and then tweak the LiveTV bitrates/quality options up 
from there if it works.  You will also find that if you don't watch 
something while recording you can use higher bitrates for recorded shows 
using maybe the High Quality profile since the system will not be 
playing back at the same time.
