Why should I need to explain it.... if dolby site suggest that surround == side channels, then I would think software like powerdvd and mpc-hc should respect this, instead of basing mpc-hc's workings on other software?

I don't think we should verify mpc-hc's correctness against something like powerdvd or tmt anyways.

It clearly distinguishes that there is L and R "Surround" and L and R "Back", meaning as you seem to suggest, that powerdvd, tmt and mpc-hc are all incorrect in sending "surround" also to the "back"...... It should be sent to "Surround" or "Side" as some people call it.

I can use my Xonar to swap Back and Side in a 7.1 config, and this shows that Asus also seem to think "Surround" should mean "Side". I havn't found any reference or site to suggest otherwise... apart from the actual software that in my opinion isn't correct (ie mpc-hc, powerdvd, tmt). Of course I would be happy to be proven incorrect, in which case the likes of Asus should be contacted but Dolby seems...... like a more reliable source when it comes to this?

EDIT: Not that its more trustable, but the wikipedia page also suggests that 7.1 audio, the "surround" channels go to the sides, distinct from the "surround back" which go to the back.
