[mythtv-users] stutter while recording two programs at once

I've got an AMD64 box with a SATA II drive formatted as JFS dedicated
to recorded programs. music, photo, videos are on a separate SATA
drive and the system runs from a PATA drive - all are 7200 RPM with
8MB buffers.
I've got a PVR-350 and an HD-5500 card in the box which is also my
frontend. I'm getting weird stuttering when recording on both tuners
at the same time. The HD stream looks perfect but the stream from the
PVR-350 will show a single frame from about a second before the
current position. It happens intermittently but often enough to be
REALLY annoying. I've found that it's in the recording this way since
the rogue frames happen at the same place when I play back every
time. I have a feeling it MIGHT only be happening when watching a
program and recording two others at the same time. I had anticipated
3GB/sec on the SATAII drive would be enough bandwidth to watch 1,
record 2. Is this not the case? Is there a good way to test? Do I
finally need to submit and start transcoding every program I watch
and deal with sub-par quality?
Thanks,
Brad
