Ok so I just picked up a Nexus S 4G and i'm loving it. Came from the samsung epic 4g and glad I made the switch. There's only 1 quirk I have about it besides the back button occasionally freezing, mine seems to have a problem with playing back a movie that my father played flawlessly on his tmobile G2X. I have preloaded a blu-ray rip of the remastered ALIENS (great movie BTW) and it plays but I cannot fast forward the movie. It's some wierd thing with it, if i try to drag the playback bar it fast forwards, but only like 20 seconds no matter how long I drag it. It has been converted to an mp4 file and is about 3GB big. I have tried moboplayer and Summerplayer and both do the same thing. Does anyone know how to fix this?
