This is how my Media Composer (version 8.3.1) window looks: The audio plays fine but no video. The computer is connected to a flat screen TV via HDMI, would this effect Media Composer playback? Any idea? Thanks Manuela Shane Ross replied 8 years, 10 months ago 2 Members · 1 Reply 1 Reply Shane Ross October 4, 2017 at 5:50 pm What happens when you disconnect that cable from the TV, does it work fine? or are you using the TV as your computer diplay? Or tryng to use it as second display and do full screen playback on it? Shane Little Frog Post Read my blog, Little Frog in High Def Reply to this Discussion!
