If you're mad keen on a band that produced their music through the 70s or 80s (think Pink Floyd), you've probably spent time collecting both their CDs and rare tracks. Video performances will have been made available, but most likely imported to a computer and then encoded with an old codec that isn't supported by the mainstream video players, such as RealTime or QuickTime. Alternatively, it could have been encoded by a Mac-based codec, thus is not supported by Windows Media Player.02 Apr 2009
