None of these map to the driver installed.
The driver that was loaded is as follows:
Creative AudioPCI (ES1371,ES1373)(WDM)
C:\Windows\system32\drivers\...
dmk.sys, es1371mp.sys, portcls.sys
File Version 6.0.6000.16386 (vista_rtm.061101-2205)

The Video problems seem to have been described elsewhere as a future update to the virtual video driver.
The lasting issue is inconsistent USB drive mounting and an emerging problem with lost mouse clicks. (thats new)
Will continue testing and gather some more information regarding the mouse.
Thanks for a good beta guys.
