I just recently purchased a set of Motorola S9-HD bluetooth headphones. I love them. When I listen to Pandora, Slacker, or just music on my Evo, it plays fine. However, watching video through Rockplayer, video sound stutters. I thought maybe it was Rockplayer, so I tried DVD Catalyst Free to convert the file, played through the stock video player, and it still stutters. Any ideas as to why?
