Has this been fixed? It also happens with Windows 7 by the way. It's really my only big problem with the Nvidia HDMI solutions (I got the Asus 9300 mGPU board and a 9200m GS laptop with the same issue). Using 1.0.0.37 here. I'm surprised there isn't a lot of noise about this, aren't people using 7.1 setups? What kind of self-respecting geeks are you?

There are a couple of workarounds, so for now it's not a huge deal. With PowerDVD Ultra, when choosing HDMI/PCM output it apparently bypasses the channel assignment of the driver/Vista, so the sides/rears are OK. But when choosing 8-speaker output they do get mixed up. With Arcsoft TMT, it didn't happen, but since I've read some comments on how Arcsoft also mixed the sides/rear, I am suspecting (haven't tested thoroughly) that there's a double-mixing going on there, thus actually ouputting the rear/sides correctly with Nvidia HDMI solutions.
By the way, Tim, I've read a few of your other posts, since we seem to have similar setups and the same troubles (I got an Onkyo 606). Don't know if this got resolved, but you can switch on/off Vista Media Center from bitstreaming DD and DTS (thus be able to enable VMC sound effects), by going into the Vista playback devices menu, and either disabling Dolby Digital and DTS Audio under the "Supported Formats" tab, or (less desirably) unchecking "Allow applications to take exclusive control of this device" under the Advanced tab.
Oh, and if you want DD or DTS bitstream through the HDMI for Media Player Classic, (or anything that can use AC3 Filter), just enable AC3Filter and output to S/PDIF, and make sure you have the options above checked (same as for Media Center).
bingobill, (sorry if this is dated), Dolby Digital EX is not undesirable (and in some instances, DPLIIx movie), because DD EX content would have been encoded specifically for EX (similarly with some DPLII content), and with EX, it actually has a flag that tells the decoder to enable EX if it's available.
