Hauppauge has been nothing but trouble with me, though I had one of the earlier generation cards - I can only hope they've improved since.
The bundled software sucked, and there was no support for 3rd party programs really - that excludes Media Center from the picture as no BDA compatible drivers. The updated I got from the hauppage site, I discovered to not be compatible with my card - even though it was under the correct model number. I ended up having to contact technical support, who told me that my card might have been a separate batch with the same product key, and eventually had to battle my way through their FTP site to find compatible drivers - was very much a case of trial and error.
I've got two digital cards at the moment and I'm very pleased with them. One PCI, the other PCI-E, but I can't tell you the names of them other than the chipset they posess: Phillips SAA7162.
Hope that's somewhat helpful.
