I use Media Center in conjunction with my PS3 to watch TV shows and movies on my large screen TV. I generally don't usually have trouble with the TV shows, which are around 350mb/hour, but I have a ton of trouble with movies. The trouble is always the same, play a few seconds, stop, play a few seconds, stop, etc. I am assuming it is a buffering issue , but wonder why the size of the file would make a difference. Has anyone else experienced this and found a cure?
