I am only able to tune to those HDTV channels if I first tune to a non HDTV channel on the same transponder. Are the disecq/transponder change not transmitted from the budget through the FF card to the dishes ?
Both cards send the signals for the disecq/transponder change. As your problem sounds strange, I ask you to try the new logging function of the LNB-sharing patch for vdr 1.3.33. Turn it on, and grep syslog for "LNB" afterwards.
