If pausing a move, movie continues when play is hit, however no other movie will load after

I don’t know if anyone else has had this happen, but if i’m watching a movie, and i hit pause, and leave for about 5 minutes, i can come back, resume and finish the film. However, if i try to watch any other movie, i can’t get it to start. I get the movie listings, the choice between DVD/HD and even the source. however, once i click on the source, megaupload loads, i see the loading circle, and a glimpse of a play button, but then it just shows the Source page again. The only way i have been able to get things playing again, is if i re-jailbreak. Anybody else know of a fix for this?

 

Thanks in advance.
