Win-7 RC 7100 is working reasonably well except for occasional crashes due to video card (Sapphire 1950Pro) and M-Audio 5.1 drivers
My ancient ATI HDTV Wonder plays remarkably well using WMC. The problem I'm having is that the OTA Tuner will not play any HD DTV channels above 9.x. It tunes VHF 4.1 and UHF 27.1, 27.2 and 27.3 but will not tune any others i.e. 13.1, 13.2, etc. The guide shows the channels but no signal.
Win-XP plays them all under ATI"s poorly designed software.
