Progress at last! I tried the onboard video out to display gbpvr, and was still getting the same problem, so the hauppauge card wasn't to blame.
In desperation, I pulled the earth wire out of the power supply plug, and bingo! no interference on the picture or the sound. Seems as though I may have a dodgy earth in my new property - my pet electrician is coming tomorrow, so I'll get him to check it.
At least I can get on with configuring the rest of my new pvr system!
Thanks to all who responded - your help was very valuable in tracking down the problem!
