Clickfinder problem with same channel on different cards

[sunflower]

Hi,
in general my clickfinder based epg works fine, but I got one issue:
As I use both dvb-c and dvb-s, I often got the same channels on both cards. I tried to map both channels to the appropriate clickfinder entry, but the EPG always works only for one of both channels.
Mapping the channels is somewhat difficult, as the plugin uses the 'real' channel name instead of the 'display cannel name' (which would tell me wether it is the dvb-c or or the dvb-s channel).
Any hints?
