No, the Vista Drivers didn't resolve this issue. I actually had this issue back when I was running XP. I posed the original question while you were engrossed in getting DVDLobby 3.75 out so I think this just got swept under the rug. I haven't brought it back up since I've had all the trouble with my system, and now that it is working like it was when I was running XP, I thought I'd revisit the issue.
As far as logs go, what do you need? The logs I provided on the first page of this post are not enough? Let me know what you need and I'll provide it to you... provided I can figure out how to.
