Also, is there a way to keep links to channels in bouquets after deleting them, like when we delete a full satellite using stb interface, links to channels are kept on bouquets and they will show up again after a new scan/lamedb import. The way I see it, E-Channelizer deletes all entries from bouquets corresponding to channels deleted.
Yes! go to Satellites > Edit. delete the satellite(s) you want. When prompted, select No to delete the satellites only without removing the corresponding services.
That will delete the selected satellite entry from satellites.xml, satellite will vanish with all transponders, surely not want we want.
Should be a way to delete channels from lamedb and keep links in bouquets. Like I said before, you can delete channels, but there's no way to keep them in bouquets after deleting.
There's two ways of deleting channels now, deleting them one by one from list or going to "Transponders", select satellite and "delete", this way all channels from that sat will be gone.
At both situations, should be a prompt like "Keep links in bouquets (for schedule rescan)?"...
This is certainly possible, you can do this with enigma2 interface - channel list > all sats > menu > delete selected satellite, or manually by clearing lamedb.
After this, all channels references still in bouquets but not available, a rescan wil make available again (if no reference changes)
