I was having a few problems with my set-up so i decided to do some investigation. I found that when recording multiple sky channels using WMC, that when i got to a fourth channel OSCAM would have the highest numbered viewer change from active to connected. On switching back to this channel it was know black. The same thing happens when i decrease the tuner count to three now on the third recording the first recording stops
