I posted this on the iTunes section and did not get solutions for my problem. I hooked-up my MacBook Pro to my Sony Bravia HDTV to watch iTune movies and use my computer at the same time (non-mirrored in monitor preferences). iTunes movies play on my HDTV when they are not maximized in iTunes. When I maximize the movie, it reverts back to my MacBook screen and the HDTV screen goes blank. I reviewed all my display preferences and cannot find any options to fix this. Another question, will HD iTunes movies display properly on a 52" HDTV screen at 1080p? It seems that some of the movies I have played so far seem grainy and jerky at minimized screen (since I can't maximize it). Basically, I want to match the quality of a HD movie DVD. Any experiences with this or am I wasting my time? Shouldn't using a MacBook Pro be like using AppleTV with regard to video quality? MacBookPro 2.53ghz; 4gb RAM Thanks!
