Yep, but i think you're aiming at v6 being able to work with AVCHD natively.
This is no solution in this case, as i also want to be able to replace 
sound, and add (custom) timecode to the files.

What i'm doing:
FFMBC.exe -i "N:\02\New folder\AR25MAY064.MTS" -vcodec copy -acodec 
pcm_s16le "N:\02\New folder\AR25MAY064.mov""

FFmbc version 0.7-rc7

Result plays fine in QTplayer and VLC, but is 'garbled' (on some frames) in 
Avid, on both playback and transcode.
Stepping backwards frame by frame seem to be better, perhaps that's a clue..

Any ideas?

thx,
