i I don't have an answer for you but like your question. When I first bought my Epic 4G I was able to watch videos w/out any problems. However, for the past 4 or 5 mo I have had nothing but continuous issues watching or attempting to watch videos. I have yet to figure out why or find a solution to my problem.....it's been so frustrating that I've pretty much given up on trying...at least for now. Hopefully one day, when I have the time, I will get this resolved! Good luck finding an answer to your question. Wish I could help. :-\
