[quote name='tomdolizong']Does the PS3 not have either?
Thanks[/QUOTE]
I believe it decodes it, but it passes the signal as uncompressed 7.1 PCM over HDMI. Optical connection only supports DTS 5.1 I believe, but that should be the case with any HD player. It's not high enough bandwidth.
Honestly, it's not that big of a deal if you ask me. Uncompressed PCM is pretty damn good. Most players, let alone receivers, don't support the bitstream mode necessary to maintain True HD 7.1 the whole way.
I think the upcoming Amazon PS3 deals for $200 are insane. If you can score one of them, that's the way to go. Some people don't like the lack of IR, but you can overcome that with a 3rd party remote + IR receiver. A Harmony remote should run around $60 and the receiver can be had for about $10. The only thing you're missing is the power button, which bothers some more than others. You can turn the system off through the PS3 menus, but to turn it on, you have to hit the power button on the system or pop in a disc. It's better to have a blu-ray player that doubles as a next-gen console IMO.
