AVCHD uses H.264 video and AC3 audio in m2ts but some of the camcorder makers use alternate extensions like m2t or mts, its the same thing they stupidly cant agree on just using one.
The camcorder makers definitely do wacky things, I once saw a AVCHD Panasonic output H.264/MP4 files that were unplayable on a WDTV Live but played fine in XBMC.
Those 1080p @ 60Hz camcorders are actually breaking the AVCHD spec, they use H.264 High Profile @ Level 4.2 and I think the Crystal HD handles up to Level 4.1 though I don't know if that ultimately makes any major difference.
