OK, after reading bunch of reviews and forums, Im confused about the Logitech Z506 sound system....

I want to get some speakers for my PS3 (current sound system unfortunately does not fit new cabinet/lounge area) so i can watch movies etc without relying on just the TV speakers (which fail miserably on blu-rays :) ) but some info Ive read says that the speakers wont be running in 5.1 for a console, just stereo with the "Matrix" mode enabled, and willl only do the 5.1 on a PC with a 5.1+ sound card.

Are they or are they not 5.1 for PS3 ?

If anyone can shed some light in the next hour or so, it would be appreciated before I goto Playtech and buy some ;)
