 Thanks.
You should be able to watch other streams at the same time.
The recording is done in a background thread with an external ffmpeg.

However if your provider limits you to one stream at a time you won't be able to.

Also, if you record from plugin:// urls (ie addon links) when the recording starts it will stop whatever is playing to work out what url it resolves to.
You can restart whatever you were watching after that.

So, in the normal case when your m3u is just full of http:// links that can all be played at the same time, you can record as many programs at the same time as your bandwidth and cpu allow. 

  hm.. Strange. I do record from a simple http:// link and as soon as I record I can't watch streams from plugins. If I try to start a stream from the dr tv addon it loads for a while and starts 'playing' but there's no audio or video. Wonder if there's something in my video settings..
