Hi,

i would like to convert this TEST.MTS file to something more usable in Avid Mediacomposer
but sofar all programs tested  (Avid, VLC, FFmpeg, FFmbc, MpegStreamClip Mplayer & Quicktime )
failed to decode the file properly, most of the time you get some decode macroblocks at the 
top of the picture but about 80 % remains green, we have some audio but decoding is poor.

ffprobe gives the following output.

# ffprobe -pretty TEST.MTS

Any ideas what to try
