Phoenix, you may get better results just looking for two separate devices - one for your 5.1 output, another for your recording input. From the digging that I've done on a semi-similar subject, it seems that cards that do one well don't do the other, as people who do recording generally don't care about surround output and vice versa.
My suggestion is this: Grab the Chaintech card for your 5.1, and for your recording, pick up an M-Audio MobilePre. The MobilePre is an external FireWire box, but does recording quite well.
