The same problem exists in setups which use an DXR3-card as output device, 
so that vdr always has to be in transfer-mode. Several members on the 
dxr3plugin-users mailing list seem to have this problem.

With my setup (using one full-featured and one budget DVB-s), I only get 
the black screen when a recording starts. Normally the budget card is the 
source for the transfer mode, but it is also used for the first 
It seems, if the epg-scan has started before the recording started, the 
first (full-featured) card does the epg-scan. If the transfer mode has to 
be stopped on the second card, it doesn't get switched correctly to the 
first card (the logfiles suggest that the epg-scan continues).
Maybe there is a problem in vdr that prevents the correct selection of 
receiving cards.
One thing I noticed: The comments in cDevice::GetDevice() seem to indicate 
that vdr distinguishes full-featured and budget cards with an 
HasDecoder()-call, which returns true for dxr3-devices.
