I'm reformatting this week and plan to go Win2k all the way instead of this dual-boot I got going on now. One last concern is with my DVD software...I know it will work but I'm concerned about the surround sound. I have an SB Live 5.1 coupled with my Altec Lansing ADA890s to get my surround sound. I've heard rumors that this doesn't work in Windows 2000. In Windows ME I've been using PowerDVD v2.55....should I use this or v3.0 in Windows 2000?
