There are still some remaining artefacts though. But I then tried the card in my Athlon machine and it works correctly. I wish I'd done that earlier now. My excuse is that I really didn't want to upset my working MythTV system. So I guess the PCI related theories look good and it's something to do with the motherboard / chipset. It would be nice to get the older machine working but it's not essential for testing / working on the Myth DVB code now I know it's going to be usable!
