I'm happy to to read that you're doing better as for The Tunnel plays great plus it nice to see it 720p.

Sorry you're sick hope you feel better soon.

Ok so I tried them in Windows XP 32 bit with vlc player and got some stutters when as they opened for a sec or 2 but that's it.

Well I got no stutters from any of the formats but that may have to do with the player and maybe the OS. I'm using Vlc on Ubuntu 10.04 32 bit Linux as for what format I vote for is Mkv but i'm fine with Mp4 as well I will have test this in windows later.

I would say MKV it has better flexibility in codec and parameters from personal experience I can say it is the best video and audio container format out there that and most multimedia players play it.
