I've just found out that there's an issue with DirectX9.0b ... For ATI AIW PAL products it stops the TV function from working!!! What's more frustrating is that ATI say you must install DirectX9.0b prior to installing MMC 8.5 Anyway, MS are working on a fix apparently and news will be posted to the ATI site at some point. So I'd suggest sticking with 8.? or 9.0a at the moment. Mark.
