AC3 Audio for PS3

[Nash]

Hi all, hope you can help with a basic question that may have been answered but I can't find it.

Is there any way I can stream AC3 Audio whether Dolby Digital or DTS to my Xbox 360 or PS3?

Twonky works really well for both audio & video but I am trying to compare Twonky with a n other but neither can stream 5.1,

thanks

Nash
