Know that there is a great working beta driver out for Terratec PCI HD card. I have dual cards installed on my system, and it was working terrible with the official driver (1.01.01.501).
After installing the beta driver (1.01.02.401c Beta) on my Windows 7 x64, everything is working great, no more problems on switching channels, when one card starts recording, I had difficulty changing channels etc. which I do not have any problem at all anymore. And card sharing with NewCmd is still working, I can use the same Ziggo card for two tuners at once.
A warning though, I had great difficulty on installing the beta drivers, after a few boots and struggling, driver worked for one of my cards, and a few more tries and second card kicked in also. Now everything just works fine without any fiddling. I advise you to stop TV server before installing the beta drivers so that installer can install the files (I think that's why it failed on my system initially)
Good luck
And I do not need to use restart graph debug option anymore to be able to switch channels, switching is faster now
