Hey Nighthawk,
I got my original PowerDVD XP 4.0 version, which has 6 channel capabilities, with my Hercules Muse DVD 5.1 sound card. I did an upgrade patch a few months back, and I am a registered user. They sent me an email just this weekend about 5.0 Deluxe.
They have several upgrade options with different price breaks. It depends which version you currently have, but they do a good job of explaining that. Here's the link.

BTW. I use the Dolby headphone option last night with my Sennheiser headphones, and it blew me away!
