Ok, so I have changed the DiSEqC setup in my VDR to S19.2E 11700 V 9750 t v W15 [E0 10 38 F0] W15 A W15 t S19.2E 99999 V 10600 t v W15 [E0 10 38 F1] W15 A W15 T S19.2E 11700 H 9750 t V W15 [E0 10 38 F2] W15 A W15 t S19.2E 99999 H 10600 t V W15 [E0 10 38 F3] W15 A W15 T which should be what the "spec" requires, right? Not much to my surprize this doesn't work, either. The multiswitch I use ignores any "analog" switching stuff as soon as it receives the first actual DiSEqC sequence. So doing the t-v-A-t dance doesn't make any sense. I also updated the driver to the latest CVS (2004-03-15, 17:31), compiled both driver and VDR newly, but there was no improvement. So all I can say is that I still believe DiSEqC handling is broken in the current dvb-kernel driver.
