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.
