common http based ogg streams broken in Vista WMP (atleast vista 64)
I tested these links on latest available Unstable pack installed on Windows 2003: http://theclassicalstation.org/internet.shtml#Ogg (click Listen for .m3u based link) http://ogg2.as34763.net/vr160.ogg (direct link to Absolute Radio ogg)
Those work on WMP that comes with Win 2003, .pls based link to the above vr160.ogg does not work.
None of the above work in the WMP on Vista 64 bit. In GraphEdit on Vista 64 atleast the direct .ogg link works using Render URL from the menu.
