I'm confused now, Para.
Post 21 above suggests that there are problems with that.
Whereas you agreed with CBA_Caption's post regarding the Yamaha Av set up. (Post 24).
I'm running Vista MCE by the way so I really don't want to start screwing around with new hardware and buggy software.
In addition, the way things are going, a stand alone blu ray player in addition to my HTPC, that will run through an av receiver seems a lot less hard work. I know, the concept of 'all in one box' is getting stretched but you know what I mean.
Thanks again for all the advice.
