XiphQT 0.1.5 (windows) does not support files with .oga file extension
I was recently testing playback of various files in iTunes.
On a WinXP machine I'm able to playback a set of .mp3, .ogg, and .oga files using Songbird.
On a Windows Vista machine + iTunes + XiphQT 0.1.5 I'm able to playback the .ogg files, but the .oga files don't appear to be recognized or imported in iTunes.
