None of the 720p WMV game videos from Microsoft sites (Turn 10, Bungie) work properly on my PS3. Video is fine but the audio codec doesn't work. Forcing me to watch them on my 360 (which is annoyingly loud)
Is MS deliberately using an audio format unplayable on PS3?
Isn't there a setting somewhere for enabling WMA, something you have to register through the settings, like the DivX thing? Maybe you didn't do that yet on your PS3?
