Thnx for the reply, I think it being a higher res file is probably the problem. But theres something else that puzzles me, the file i have is just a 500 mb file that the guy claimed is 720p and it is in terms of resolution but probably the bitrate has been reduced considerably to make it 500mb.
I installed VLC and tried playin it but i only see like 2 frames of picture play and then hangs on the latter frame and then only sound continues playing...wierd!!!
