Two Channel -- DTS Master - HD Audio?

Have a two-channel system. Just put a hdtv in the mix. Feeding toslink from ps3 blu ray to two-channel dac. Understand this will not provide the hd audio. Questions, which I can't seem to find the answer to, is it possible to even get lossless audio from blu ray to two-channel system? Do I need a blu ray player that decodes and then use two-channel analog out to get this? Do blu ray players do this? Is something lost taking the multi-channel high rez audio down to two-channel in the since of whether it's still lossless (not benefits of two-channel v. multi-channel)? Worth the money to get the lossless, and if so, cheapest sonically sound route to go? Thanks for any information you can provide.
Answers to your questions:
1. Yes.
2. Yes.
3. Yes.
4. Nothing is lost except the surround effect. It is still lossless.
5. Cannot say. It depends on what your equipment and ears tell you.

I believe that a current AVR will take the multi channels of HD audio and output it into whatever channels you have available, in your case 2.0. I'm not sure if you'd get the same results using a blu-ray player that could output multiple analog discrete channels and only use two of them. Maybe the players are smart enough to combine the total signals into less channels.
Most modern players have decent channel management and easily output 2.0 (or any other channel configuration) from HD tracks.

Thank you for the responses. To my ears lossless is generally worth it. A new player is probably less expensive than other options, so I'll probably start checking there. If anyone has a recommendation on a player for this purpose, please tell me. Thanks again, skf
If you believe in the wisdom of crowds (and reviewers) you can't go wrong with the Oppo 95 (especially if you are limited to a 2 channel application).
I second the Oppo 95. Two words : ABSOLUTELY INCREDIBLE!
