There are quite a few movies out there where an OST is not available.

I want to make one by ripping the music from the DVD. This has been fairly successful before where there is a 5.1 track available and all spoken bits come out of the centre channel only.

The movie I'm working on now, although has a 5.1 track, it seems dialogue also come out of the front L/R speakers. Is it possible remove these sounds from the music, or any techniques to subdue them?

Also are there any tips of normalising the levels to make all songs coherent and suitable for listening?

Thanks.
