Yamaha RX-A1000 - rear speaker output with a 5.1 source? (1 Viewer)

[danwnz]

Well here's my first post...
I've been using a Yamaha RX-A1000 receiver through my 7.1 speaker set up for a few months at home and generally I'm very happy with it, with one exception...
My old Denon AVR-3805 had a feature where a 5.1 source (eg dolby digital or DTS) it could output to the rear speakers as well as the surround (for those with 7.1 speaker set-ups), so outputting 7.1 from 5.1. I imagine the rear speakers were probably just mirroring the surrounds. The newer Yamaha doesn't seem to be able to do this. I can get 7.1 fine from a 2.0 source via Prologic II cinema, DTS Neo or the receivers "CinemaDSP" setting. However when I switch to a multi channel (5.1) source I can only ever get 5.1. I'd really like to get some sound from the rears, even if just for presence.
Any suggestions?

It has DPL IIx...so, not sure why IIx isn't working.

Thanks for your quick reply. I searched a little deeper and under an options menu there IS an option for "extended surround" . Changed this from "Auto" to PLIIx and all fixed.
