I don't understand what you mean. It just modifies the algorithm to
prefer receiving devices on the same transponder that have priority>=0
receivers or transfer mode receivers. Before the patch it would prefer
any receiving devices on the same transponder, causing osdteletext
receiver to make a difference.
- user watches transponder 1 channel 1 through primary FF
- recording starts on transponder 1 channel 2
Before this patch:
- if osdteletext has a receiver on FF, the recording is made via FF
(Receiving(true) is true), otherwise via budget card
After this patch:
- recording is made via budget card (same behaviour as VDR 1.4.1)
The alternative (more logical) fix would be to prefer transponder-tuned
primary devices too, so that the recording in above example would be
made by FF as it is tuned in the same transponder. But this would
probably not be a good idea (at least without YASO) due to the apparent
problems with recording via FF.
However, one possibility is to prefer the FF for recording in this
situation by default (which would leave the budget card free), and also
in the original situation (in which the budget has CAM), and have a
setup option for Avoiding primary device for recording at all cost.
