I forgot to mention that there is a legitimate use for this patch. BBC Parliment channel carries 1 video stream and 3 audio streams. The video stream contains three smaller streams comprising of 2x BBC News 24 Interactive and 1x BBC Parliment. The 3 audio streams correspond to each video stream. At the moment you have to use +/- to change the audio channel. At some point in the future these will work like they do on a set top box, ie. The interactive stuff will all work, but that's a work in progress. (I'm working on it, but it'll take a while..) Stuart
