I've checked my TechniSat receiver: the time between two DiSEqC messages is about 1000 ms. I've changed my VDR patch accordingly and didn't see any tuning timeouts so far (i. e. the tuner got a lock within 1000 ms). Maybe it would be a good idea to have an ioctl() for the frontend to continue it's current tuning operation after a DiSEqC message. Bye. -- Dipl.-Inform. (FH) Reinhard Nissl mailto:rnissl@xxxxxx
