Win2k Pro + SP2 (applied 22 May, there are differences from the unofficial release) ATI AIW-Radeon SB Live! 5.1 w/ Live Drive Cambridge Soundworks DTT3550 LiveWare speaker settings: 5.1 speakers Advanced: AC-3 off, Digital output DTT3550 settings: Fourpoint/5.1 DIN Dolby Digial/PCM Audio: Digital DIN .. NO OTHER SELECTIONS for DVD! DVD: X-Men PowerDVD 3: set to SPDIF output Tested with the THX audio test in X-Men, and got all speakers to sound. Interestingly, LiveWare's speaker test fails with these settings (but succeed with DD/PCM Audio turned off, and Multi-Channel set to Digital DIN). I'm currently 25 minutes into the movie and the synchronization problem is non-existant, except in one instance where I was messing with the Windows speaker control. Pause/unpause immediately cleared the problem. WinDVD 2000M: no luck

You must use the Windows XP driver, not the default Vista driver.

You can also use an alternative driver made by other people, search for Vista sound blaster live driver alternative. But this did not work with me.
