Be aware that if you have the PC decode it and send PCM through the optical connection you will only get 2 ch audio. You will not get 5.1

If you still want to get 5.1 surround and your receiver only supports DD, there are motherboards and/or sound cards that support the decoding of surround tracks and then re-encode them into Dolby Digital 5.1 in real time. This would then be sent out the Optical port to the receiver and the receiver will then process it just like it would normally process Dolby Digital soundtracks.

Has anyone heard of this technology?

Thanks, I think that's what it's called. I found something interesting though:
