I am having a similar problem as the original poster. My HD works for a
little while then I need to reboot the computer to get it to work again.
When it does work I get artifacts and long signal detection times. The
system it is running on is a Athlon 64 3200 single core processor with the
pcHDTV 3000. I am not sure what is happening. I am not sure if it is myth,
the power supply, or whatever. I am wondering if the power supply is
marginal and therefore creating some instabilities. It only happens when the
HD card is in use and only after an hour o so.
