Hi Benedict,

I understand you want to use Cinelerra but anyway, I've been editing a 
lot of AVCHD (actually AVCHD 2.0/3D) with AC-3 Stereo sound (and 5.1 
using some workarounds) quite happily with kdenlive. It has a convenient 
feature to transcode AVCHD to DNxHD and I found it much more functional, 
user-friendly and stable than Cinelerra which I think is a usability 

The transcoding profiles of kdenlive simply copy the audio stream and 
for me the resulting DNxHD files worked very well for editing.

I also used the .MTS from the STREAM directory and I am not aware that 
there are any alternatives.
