i don't have nero vision but what exactly does that have to do with a tv tuner?
You would think nothing...but the driver for my current card, the AverMedia M791 (an OEM card installed in Gateway computers) conflicts with Nero Vision.
With the driver installed, Nero Vision crashes, actually it shuts down with no warning for no apparent reason. Once I uninstall the AverMedia driver Nero Vision works perfectly. If I reinstall the driver, Nero still works fine until I reboot the computer, then the problems start all over again. I can't get any hardware or software vendor involved in this conflict to offer any assistance - Gateway said that since Nero didn't ship with its computer, that I should uninstall it, swallow the blue pill, stop worrying and learn to love the bomb, etc. (FWIW, the Gateway chat tech closed the chat on me after telling me that I should never have even thought of installing Nero on the computer.) AverMedia doesn't have any plans to update the driver for this particular card even though the driver file is now over a year old. And Nero hasn't even acknowledged my technical support submission yet.
Doing some research, I've discovered that the WinTV-HVR-1800 shares many of the same chips as the AverMedia M791; however, the ATI 650 shares no common chips with either of these cards. The last thing I want to do is buy a new card with the same issues as the old card. Therefore, I'm now leaning towards the ATI card. The specs are what I want (PCIe, ATSC/ClearQAM/NTSC, hardware encoding), so I thank you for your suggestion.
ClearQAM is used by cable companies to deliver unencrypted HD content over cable lines - generally, your local HD stations, thus eliminating the need for an OTA antenna or set-top box to get your local stations in HD. The Vista Media Center TV Pack will allow you to use ClearQAM in Vista Media Center...or so a little birdie told me...
