A problem...

I have tried 4.1, 4.2 & 5.1, with two different USB DVB-T tuners (dib0700 & AF9015), same prolem every time.

I have a DVB-T channel selected . Start recording. When I zap to a DVB-S channel, the recording stream stops, although the recording light on the front of the box is still lit, and the timer continues. If I zap back to the DVB-T channel, the stream/file on disk starts again.

What's going on? Can this be easily fixed? I don't see any reports of this behaviour in the forum, am I really the first to notice this? I'm using the stock images, no plugins except the tuner drivers.
