Unclear about Channels Tab in config

[htewam]

I've been using gbpvr for about a year now so not a complete novice -- I'm just not a sophisticated user. I recently got fed up with my cable company jacking up the rates and downgraded to "limited cable". This means that zap2it is continuing to give me listings for specific channels that have now been blocked.

My confusion starts in config, where there are channel listings BOTH in the Capture Sources -> Edit Recording Source area AND in the Channels Tab. I looked on the wiki and on the forum and I get bits & pieces of the answers but not enough to truly understand the inter-relationship of these two sets of menus.

Questions about the Capture Sources -> Edit Recording Source:
a) When would you uncheck the "Enabled" box for a specific channel?
b) When would you highlight the channel and then hit the Remove button?
c) All my changes made here seem to get undone if I empty/reload the EPG... is this expected?

Questions about the Channels Tab:
a) When would you uncheck the "Favourites" box for a specific channel?
b) When would you hit the button "Remove unreferenced channels" and what is the effect?

After fumbling around trying different combinations, I was finally able to get what I was after... limiting the number of channels in the EPG to what my limited cable service is now offering.

The channels listed in your capture source are the channels received by that specific capture source. The channels tab list the superset of all channels from all capture sources.

Questions about the Capture Sources -> Edit Recording Source:
a) When would you uncheck the "Enabled" box for a specific channel?

Its expected that most people will have all channels enabled. These are the channels that will be listed in your tv guide etc. You should untick this if its supplied in you EPG listings, but not a channel you can watch.

b) When would you highlight the channel and then hit the Remove button?

Rarely. Usually only if you've manually created a channel and want to get rid of it, or if your cable company as moved some channels around and you've end up with some channel that no longer exists but is shown in your list.

c) All my changes made here seem to get undone if I empty/reload the EPG... is this expected?

Any channels in your listings which dont exist in GB-PVR will be created as part of your EPG update. You'd need to either untick the enabled check box (it'll continue to process listings for that channel, but not show them in the app), or preferrably to remove the channel from the source if you can. So for zap2it you could log into http://labs.zap2it.com and remove the channels from your channel lineup.

Questions about the Channels Tab:
a) When would you uncheck the "Favourites" box for a specific channel?

This does nothing currently. It used to many release ago, and is functioning again for the next release. Pressing up/down to change channels will only change between favourite channls, but you can still get to the rest via the TV Guide or mini guide or by typing the channel number. All channels are favourites by default.

b) When would you hit the button "Remove unreferenced channels" and what is the effect?

This does a clean up by removing any channels that are in the master list, but not referred to by any capture source or recording.
