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 found the subtitles I needed; I'm testing the muxing of all the audio tracks and subtitles with TSmuxer, using the first test version I did... and I confess I'm enjoing to be a "producer" ;-)
If it works well, I'll start the encoding soon - it will take more than two days with my poor old computer...
