12360	duplicated channels on different frequencies appear duplicated in the same mplexid	primijos@…		"
Hi, currently running mythtvversion: master [v0.28-pre-2477-g2ad4fa6]

Suppose this situation (dvb-t, Spain):

frequency 554MHz is a multiplex with 4 channels (La 1, La 2, 24h and Clan)
frequency 818MHz is a multiplex with 4 channels (La 1, La 2, 24h and Clan)

actually, frequency 818MHz is being removed from the available dvb spectrum in order to use it to 4G mobile data (I guess), but, for a given period of time (>6 months), the channels listed above are being broadcast in both the old frequency (818MHz) and the new frequency (554MHz) with the same data.

Whenever a do a channel scan in all transports, mythtv claims to find channels in both of those transports but instead of inserting 4 channels in database linked to two different dtv_multiplex rows, it inserts 8 channels in database linked to the same dtv (in this case, the old 818MHz frequency). No entry corresponding to the 554MHz frequency transponder is being inserted in the database.

I'v tried adding a 554MHz dtv_multiplex row by hand in database and linking 4 of the 8 channels to it. After that, I did remove the four old channels and the bad multiplex (818MHz) and I'm able to record and watch the manually-relocated channels without any problem.

Best,
Jose
