I can play both of these file formats in the standard VLC Player but how can I play them in RR ? Neither are listed in the list of Video File Types. I have .m3u files which point at url's for streams and I have an .xspf playlist with has a bunch of Terrestrial DVB-T Tracks

I messed with this about a year ago when I first started messing about with creating my CarPC (initially on my laptop) and I am 99% sure I had the DVB-T stations working using the playlist since it was easier to switch around between DVB-T channels, but I just cannot remember how the hell I did it.
