playing back .mt2s files

[hamisht]

Does anyone have a good method of playing back .mt2s files? I ripped 'The Aviator' just the single file that was the movie according to BDinfo. I have one 19gb file (small size i thought for a long movie in 1080p). I cant get it to play back in Media Player Classic, and when it plays in PowerDVD, its choppy, even though proper blu-ray discs play smooth.

I know its probably better to rip completely to ISO, but I just wanted to rip the movie quick, to take screenshots of it. Screenshots in PowerDVD come out pretty bad, but I figured if i could get it playing in MPC, it has a 'Save Image' function that might work better.

Any ideas how to get it going?
