I am having a Dual Core CPU, with 4GB of RAM, and a ATI HD3200 video card on my desktop machine which runs dual boot, 64 bit Windows Vista & Linux Mint 10. While running the Windows OS, There is no problem for watching the videos, even streaming videos shows the better results. But when I try to play (not streaming) video on Mint 10 then it shows much disappointing results as videos gets choppy and it does not gets full screen. Even when player is in full screen mode, Video stays small. I have tried to play the same video on 5 different players but all of them were working similarly. Can anybody tell me what could be the reason for such a graphic problem?
