I agree, I had issues until I added a second drive (500GB) for recordings
only. I have a very minimal system for HD (ATSC) but after adding the second
drive and a little memory it does quite well and I hardly ever get pauses in
playback even if I'm recording two HD programs and watching another.

It's also worthwhile to do a little googling on mysql optimization.
