That sounds the same as my experience.

I could tune (something close to 100% signal strength), but both live tv
and recorded would have occasional breakup or stuttering - about every 5
to 10 seconds. OTA was fine, when I could actually get signals - only two
or three channels, often dropping the signal lock.

I would try swapping hardware until it works. Maybe even try a different
HD tuner card :-/

There were also reports on pchdtv.com forums about users (apparently)
having interference from their video cards, I tried to boot my system
headless but (AFAIR) the BIOS did not like that :-(

Someone also suggested better grounding for the board (from the board to
the motherboard I guess), I did not quite follow that.

Yeh I have broken things swapping plugging etc., it happens eventually no
matter how careful you are. I had not ever even tried replacing the power
supply before, but it was easy, it is just screwed onto the case, there
really aren't any cables (just he he-500 pluggable ones and of course the
power cord). Given you have an he-500 ... I doubt it is your power.

And those SATA connectors sure are nice compared to IDE.

If anyone wants a SP-450 let me know :)
