mnaber, u r the man! Finally got it to work! Streaming TV again as I speak....here's what I did:
1. download old drivers
http://hauppauge.lightpath.net/software ... 50_inf.zip
2. Unzip
3. I didn't even have to run hwclear, so skip that
4. Go to Device Manager/Sound, video and game controllers/ Hauppauge WinTV PVR PCI II (26xxx) / Driver / Update Driver / No, not at this time / Install from a list or specific location / Don't search. I will choose the driver to install / NOTE: Don't highlight any of the options in the next window, instead just click "Have Disk" and browse to where u unzipped the old driver and select "HCWPVRP2.inf" / u may be prompted to locate a couple more files as it installs (something like kbuser.dll and ky.sys or something like that): just do a search on your machine to locate them and select each (but don't select either file if it's located in a ServicePack folder)...
Enjoy! And again, huge thanx to mnaber!
