I think there is a problem with your patch. There is a reason for the
priority -1. Imagine you have a channel which can only be received by
one card and this card is used for transfer-mode. When you want to
switch to this channel, the transfer-mode has, with your patch, e.g
priority 0. But the new transfer-mode would have the same priority (but
not a higher), so there would be no free device (channel not available).
So when searching for a free device, vdr should consider that the
device, which is used for transfer-mode, could be free, if transfer-mode
for the current channel has ended.
