I've always wondered this.
The PS3 will output HDMI as MPCM if you set it correctly. The proper mode here to use is STRAIGHT in this case. I don't think you can get 7.1 from 5.1 movies with this option as I don't believe the 661 can apply Dolby Pro Logic IIx processing to MPCM.
If you want to apply DPL IIx, use bitstream instead, but you won't get lossless audio.
The surround mode button is for two channel sound, at least it is on all my Yamaha receivers. The Extd Surr button is for 7.1 from 5.1, but as I mentioned above, I do not believe that will work for HDMI/MPCM, but you can try it.
You can certainly live without lossless audio. See the link I post in the AVR Faq where they did listening tests on it. If you feel you can live without it, you can try setting the PS3 to bitstream mode. In that case you will be limited to DD or DTS. DD is likely always a high rate DD of 640 kbs, which is better than DVD. DTS is the same, but 1.5 Mbs DTS has always been excellent.
