.asx and .asf files fail to open properly in android
Example file http://bbc.co.uk/radio/listen/live/r6.asx On my PC VLC opens the (XML) file and loads all the streams into a playlist. On Android the file just doesn't load. The app already has the potential to play the stream if you copy and paste the mms link from inside the file so it looks like a quick fix.
Other example files can be found from http://beebotron.org but the listen again links expire quite quickly so there's no point listing them here.
