I got Win7 Pro installed and it works great. I got my OTA tuner working with Windows Media Center, but I am still trying to get it to work with my 1020a. Windows didn't automatically find any drivers for the 1020a so I installed the drivers that came on CD with the card. Windows recognizes it now and says the device is working properly, but I was unable to find it through WMC. Do I need to do anything with the software that was installed with the drivers? It has the antenna setup stuff like a receiver would have, but I'm not sure if I need to have that running as well as WMC or if WMC will do it all? I will try it tonight. When I tried to add a satellite receiver through WMC it only had info/setup options about STBs, not tuner cards. I am going to try and get it working with the VisionPlus software that came with the card and then with WMC. Hopefully I can get it working through WMC.
As a side note, when I was watching live HD content on NBC last night, it worked great. However, when I would try to view the guide while the show was still playing, things would start to get rough and the video started skipping and the system started get hung up. This is using 2GB of RAM and the on-board HD Radeon 3200 video. I have another 2GB of RAM and a Nvidia 9500 GT w/ 1GB DDR2 on the way. I'll update on the performance once I get these installed.
