same here!!!
I have a Samsung LCD, Model: LE32B651T3W, with a usb port and i watch movies via usb. The videos are .avi format and .avi is suported on the TV. Till now i did not have any problems with the format, but now i have some problems even with .avi videos that i have already watched on my TV. I was watching a BBC documentary in six parts and they are all .avi but i have watched only the first three episodes and after a while i decided to watch the 4th, but when i plug in the usb and start the video it says 'Not supported file format'. Well, i then tried the first three that i had already watched on the TV and and it doesn't play them neither,except the third.Then i tried the 5th and the 6th and the fifth is not supported, but the sixth is ok. And i have another problem with the subtitles but it is from a while ago and it happens only with older films (the most recent one is from 2001). When i play the movies on computer and attach the subtitle it goes well but when i play it on the TV it's like the first minute is ok then the second it is late only a little, then the third more and so it keeps being late more and more (the subtitle). I know that i can adjust if it doesn't match the sound but i have to do it every minute. Please help.
