I'm not converting simple stereo files, but Dolby Surround encoded stereo files... I could also convert them to stereo AC3, but as AC3 is not perfect as someone still say ("don't worry, a simple stereo track, Dolby Surround encoded, at 192kbps will be THE SAME as the PCM tracks..." - sure... as I am Napoleon the Emperor, and I'm NOT him!) so I prefer a better 5.1 AC3 @448kbps than a simpler stereo @192kbps... maybe I'm mad, but I leave this kind of track just for commentary. I want to add that, if someone will be interested in my project (apart me, of course) maybe I'll release a BD-25 version with all the PCM tracks (just re-encoded at 48khz to be standard), stereo 16bit... only those ones weight about 6GB (including the italian track too).

I have eac3to, but maybe I'm too lazy to work with it... ;-)

I agree with you completely about AC3 vs PCM and higher bitrate vs lower, I'm a big supporter of lossless audio, I'm sorry if I came across as too critical, I'm just curious.

You could encode to a 2 channel AC3 with the Dolby Surround/ProLogic matrix set, preserving the original format of the audio, and there's nothing to stop you encoding at a higher bitrate than 192kbps, in fact AVCHD allows you to push it all the way up to 640kbps if you really wanted to ;)

I'm very keen to see the results of this project, your screenshots/videos look great!
