I have used WMP for everything since 7.1. I hated that I'd make a list and then I'd double click on a file and WinAmp would overwrite the list. Anyway, WMP9 is great on Windows XP but I notice that the full screen scroll bars do not work on Win2000, wish they'd fix that but I have a feeling it is not coming since it has been a problem for 4 months. Anyway, I only have one copy of XP Pro so I just stick with 7.1 on the 2000 machines.
