Using Win7-64 Ultimate RTM and IE 8, opening an URL with wma or wmv does not work.

Opening the same file in FireFox or Opera is no problem, they use Windows Media Player just fine.

The file associations for both file types are set to Windows Media Player so it must be another issue.

This works, I found a solution to this and fixed it a week ago, but had forgotten the what registry values to change. The question then is why is it like this in a new install of Win 7 / IE 8 with no extra codecs or other media players. – vzczc Aug 24 '09 at 13:21
It might be cleared as a default, since IE 8 doesn't have to be your default browser – Ivo Flipse Aug 24 '09 at 15:39
It is my default browser – vzczc Aug 25 '09 at 10:02
Just because it is, doesn't mean Windows automatically sets it as being so ;-) – Ivo Flipse Aug 25 '09 at 10:34
