At first sight it seems so.

But with debugging output I have observed following (single card):

EPG scan is active

Timer starts recording:
   1. channel switch - EITScanner.Active still returns true
   2. recording thread starts

Main loop in vdr.c calls EITScanner.Process every second until 
ScanTimeout (20sec) is reached

Then EITScanner.Process enters processing and detects recording is in 
progress. The scanlist gets empty and after that, following calls of 
EITScanner.Active returns false. So in EPG scan "over night" the 
transfer thread possibly never gets startet.

When the EPG scan is triggered manually a few minutes before recording 
starts, I see that the transfer thread does not start before the 
ScanTimeout in EITScanner.Process is reached. Then EITScanner.Acivity 
gets called, which triggers a channel switch an the recording finally 
continues successfully.
