As I'm really bothered when the audio track is out of sync for more than about 20ms, I would surely be aware of these kind of problem... 200ms are 5 frames (and 250ms are 6 frames), and it's impossible to anyone NOT to notice this!

But to check it out, I played the .m2ts file, listening carefully to the english LD, AC3 and DTS tracks, and none of them were out of sync... to be 100% sure, I loaded the LD and AC3 tracks in Audacity, played them together, and they were not out of sync, so... sorry, but this problem should be in your system!
