When playing the following sample in VLC: http://dl.dropbox.com/u/37259775/00800_96M.m2ts, audio and video are scrambled.
I tested VLC 1.1.11 under OS X 10.6.8 (64-bit) and Windows 7.
I also tested VLC 1.1-branch-intel64-20110918-0209 under OS X 10.6.8.
avplay (version v0.7-919-gd763fb7), ffplay (version N-32611-gd55b06b) and MPlayer (OS X Extended r14) don't play the sample particularly smoothly (at least on my machine), but it's not scrambled like in VLC.
