Both TMT and PDVD should do this for you but the sound at this point is no better than a DVD...and if you are not using a large HD screen...there is no benefit of Blu-ray at all. If you do have the right equipment it looks and sounds great.

Can anything down-convert to 5.1 AC3 / DTS instead of stereo AC3? I've tried PDVD and TMT, and unless I'm missing something, they only output 2.0 from the HD audio streams.
Obviously this isn't as good as buying a new amp and video card, but it is a lot better than watching a movie without any surround sound at all.
Thanks.

Hi Matt - I'm away for a couple of weeks but otherwise I could confirm the necessary settings in TMTs Audio Config - but it should work - here is a quote from another post on the issue that pretty well sums it up....
--- Quote ---There is no need to transcode TrueHD or DTS-MA to legacy formats. TrueHD and DTS-MA are optional codecs on BD so a mandatory codec must be included. With TrueHD there is *always a legacy DD track (it may be hidden but it's there) and TMT, PowerDVD or what ever player (even STB) will auto select the DD for S/PDIF (even if you select the TrueHD track).
DTS-MA has a legacy DTS core included and will be decoded and outputted if using S/PDIF.
*In theroy you can have a TrueHD track with no included DD track as long as a LPCM and/or DTS track(s) is included.

EDIT: Check your TMT settings (it uses its own Audio Renderer now that bypases the Win Mixer so you have to set you config in there to what you want).

Matt... I hadn't seen this thread before, but I should mention this....

What resolution are you gaming at? If you are playing on a 1080p home theater display, you do NOT need one of the high-end AMD 5870 cards. They are completely overkill for resolutions like that.
A $170 Radeon 5770 will push pretty much any game you want at 1080p resolutions with the quality settings cranked and AA turned on at 4x at around 40fps. Even the cheaper 5850 is overkill in a dramatic fashion, but if you want to make darn sure you won't have ANY stuttering ever even on Crysis, you could certainly go with one of those (or just get a second 5770 in a few months when they get cheaper).

Matt - I had a look in the ArcSoft TMT V3 Audio Settings - You can select SPDIF and then a mixing mode of either Original / DTS / DD - does this work for you?

Well, the trial of ArcSoft won't decode Dolby so I'm not sure.
PowerDVD outputs 2.0 (not surround sound) when you make the DD or DTS mixing selection. I've never been able to get it to mix to 5.1 from the high definition formats. Some Blu-rays contain 5.1 AC3, but if they don't, I'm stuck with stereo sound.
You almost have me talked into a 5xxx ATI, but I kind of want to wait for Fermi benchmarks before making that decision.
