I have some movies with SC3 5.1 and when I play em I dont get any sound in my rear spealers. Iv tried som AC3 2ch and then I have sound in all speakers.
Dosent XBMP support 5.1?
* EDIT *
Forgett it. Seams like the AC3 5.1 movies I tested play 5.1 fine in the first part of two.
Must be bad ripping... It strange tho that the first part plays 5.1 fine but not the second...
