I have just installed MP 1 Final on a clean Vista SP1 with Vista Codec Package and CoreAVC, but I simply cannot view any HD TV Channels. Everything else works fine.

I hear the sound but I have black screen in HD Channels. I have tried with ffdshow and CoreAVC as codecs for H.264 without luck. The funny thing is that is works with FireDTV Viewer.

Please, can anyone help me with this last big issue?
