Is Windows Vista supported? Yes, but there are currently a few known issues that the development team are working on. DirectSound hardware acceleration no longer exists on Vista (resulting in potentially broken support for 5.1/7.1 speakers); Skinned scrollbars may not be displayed correctly; Video playback may be a bit flaky (most likely related to old/buggy video drivers or DirectShow codecs) or doesn't work at all with Aero enabled; and DWM/Flip3D displays the built-in Classic skin for all Modern skins (note, you can enable support by setting vista_thumbnail=1 in winamp.ini, but it still won't work when Winamp is minimized). We hope to resolve most if not all of these issues in forthcoming Winamp releases.
