Problems recording TV with Windows Media Centre

[wilmac]

I recently purchased a Media Centre PC with a Compro E750 Dual Digital PCIe HD TV Tuner.
When I record a TV program I get large blocking in the picture and it is difficult to watch.
I have a clear picture when normally viewing TV and when viewing TV programs from web sites.
Does anyone have any suggestions as to what the problem maybe and how I can rectify the problem.
Please help...

Possibly it`s not letting you record, copyright infringement rules.

If you read the Compro forums, a lot of people have problems with that card and 64 bit Windows 7. Compro claim to have fixed it with the current driver which is version 1.05.520 - check yours in Device Manager.
