Following Greg's experiences in the lab, and in the absence of any non-lab "normal" install of Windows 2000, I did some testing on a computer I have at home with Windows 2000. The computer is fully updated, with Moz 2.0.0.3, WMP 9 and RealPlayer 10.5. These are the results:

• BBC on IE with WMP: OK
• BBC on IE with Real: OK
• BBC on Moz with WMP: OK
• BBC on Moz with Real: OK
• CTV on IE (WMP): OK
• CTV on Moz (WMP): OK
• CTV on Moz with Real: OK
• CNN on IE (WMP): CRASH AND BURN!
• CNN on Moz (WMP): OK

So I think we can deduce two things: First, the CNN site is completely broken for WMP 9 and IE6. That's really no loss; it's one of the most cookie- and ad-laden sites I've seen in ages, and it tries to spawn popup windows all over the place. Second, the other sites should be OK on Windows 2000, so problems in the lab with those sites are most likely caused by the Sanako player.
