Mmm, that's ugly - anything one can do about it?
question at the driver developers: is it a change in the firmware or can one
"patch" it in the driver sources? (A simple solution might even simply
deactivate the receiving/tuning capabilites - people like us don't need it at
the moment).
Let me post this to the list.
I'm not sure where the change lies, I'm guessing firmware. When fed with data to replay it also seems to check whether it has a lock on the channel it's been tuned to. If that lock fails it responds with an outcom error, then replays the data fine. Replaying and live view should be completely seperate, if at all possible in the fw.
