I have an HTPC setup using a latest gen Mac mini and a 50" Panasonic plasma TV. I have really not had any problems with my setup and watching movies via Plex. I have, however noticed that when I am streaming flash content, especially sports (watchESPN, MLBTV) there is a little bit of jitter with fast moving objects (football, baseball). I also noticed when streaming ESPN, the scrolling bar at the bottom has a lot of jitter as well. I have Comcast cable Internet and have a fast connection so I don't think it's due to my Internet speed. Is it normal for fast action using flash to have a little jitter when streaming? Anything I could do to eliminate and smooth out playback? Thanks in advance.
