Steps to reproduce:

1) having multiple channels mapped for the same TV network (e.g.: one service from DVB-T, one service from DVB-S), but as different channels in configuration (so no "merge same name" or similar).

Example:
service #1 from DVB-T -> channel 1 (a)
service #1 from DVB-S -> channel 1 (b)

they may have different resolution (SD/HD) or simply transmit on a different medium (terrestrial/Sat) and I would like to keep them explicitly differentiated for different reasons (E.g.: SAT would be interrupted in case of heavy rain)

2) They would have the same EPG, so program a recording for a given programme (e.g.: a movie) from the EPG WebUI tab.
The EPG tab will show the icon for the scheduled recording in the details column.
The DVR / Upcoming/Current recording tab will list the new entry.

3) Edit the entry from the DVR / Upcoming/Current recording tab and change the channel (with another one with the same EPG, which will have the same transmission at the same time). Save.

4) The DVR / Upcoming/Current recording tab will list the new entry with the new channel.
The EPG tab will NOT show the icon for the scheduled recording in the details column for the new channel.
The EPG tab will NOT show the icon for the scheduled recording in the details column for the previously selected channel.

Expected behaviour:
The EPG tab will show the icon for the scheduled recording in the details column for the new channel (the same programme is present at the same time).
The EPG tab will NOT show the icon for the scheduled recording in the details column for the previously selected channel (same as before).

Is this expected behaviour a possible behaviour?
