[mythtvnz] Can't record Sky Open

[Austin Green]

Sent this a few days ago but did not get my copy from the list server, so sending again in case the message went astray; apologies if you have already seen it.

Unable to record Sky Open (alias Prime) for a while.  Do I need to retune after the recent name change?  If so, can I just alter the one channel without having to do a complete rescan?  I can get Duke+1, Sky Open+1, and Eden+1, which are on the the same transponder (12519)   Have channel 1530 for Sky Open, which agrees with the LyngSat data.  Any suggestions?  Could my dish by very slightly out of line, so as to affect only the one channel?
