Problem playing HD movies from Mac pro
I have attached my Mac Pro 2008 to a HDTV using DVI. I am playing .mkv files at either 720p or 1080p. No matter what program (VLC, Flip4Mac, Miro or DivX) I use to play these files, I always get intermittent horizontal lines on my HD Screen. I can play these files with no problem on my computer screen.
Why won't my HDTV play these files cleanly?
