Same tuner different EPG configuration which one does the TV guide use?

[eramos581]

I tried finding this in the Wiki but was unable to obtain this information directly. If you have a single tuner which you add within the capture source tab as two line items with separate EPG configurations (perhaps some channel differences) by using say the MC2XML Grabber to download and create a xmltv from Microsoft MCE and another xmltv created from the TitanTV site. Once the EPG is updated for these two guys how does the TV guide know which of these it should use to display the EPG data within the TV guide?

Thanks to all in advance.

If I understood correctly, you want to use two different EPG sources to fill in the gaps (one source has a set of channels, the other one the rest of them).

As far as I understand, GBPVR will display the aggregate tv listings (source1+source2) as if it was a single source. When time comes to record, or live view a programme, it will check which tuner(s) have that channel configured/enabled/available, and act accordingly.

My guess: it would be wise not to get guides for a same channel from both sources. Doing that (same channel from both EPG sources) will probably cause havoc (overlaid instances of the same shows throughout the guide, with GBPVR trying - and failing - to deal with them).

Other than that, and since many users have separate sources/instances of the same tuner set for different inputs (to work with STB's, etc), I guess there's a distinction between separate source and separate tuner, within GBPVR, and that it will warn you about conflicting recordings regardless of how many sources, of the same tuner, you set up.

You cannot use multiple guides with a single tuner. You would need a program that would combine the two guides into one.

I've seen sub say you can. It had something to do with the broadcast EPG being incomplete, so he said create another copy of the same tuner and add an XML epg source for the missing channels. The program will know the second instance of the tuner is really the same as the first.
The key though is to make sure the same channel is not duplicated by different EPG sources, though I guess I have no idea what it will do if it does get similar but different EPG info for the same channel for multiple sources.

There is a .chl file described in the MC2XML docs (http://mc2xml.110mb.com) that will allow you to limit which channels are downloaded from each source. If you keep things tidy so that each channel only appears in one XML file or the other, and enable only the matching channels in each capture source, then there will be no possibility for confusion between the two.

I think there is also a way to combine the two XML files into one, so that you wouldn't need two capture sources defined, but I don't recall how and don't see it in the docs.

Ah yes, I forgot about this. GB-PVR is now smart enough to recognize that they are the same tuner.

I do this myself (after sub OK'd it).

Tuner 1 has source1 and source2.
Source 1 uses an internet downloaded EPG.
Source 2 uses a DVB-T aerial downloaded EPG as there are two channels that do not show in the internet EPG. Source 2 only has these two channels.

GBPVR knows that these two sources share the same tuner and there are no problems with conflicts. The EPG just shows the normal list, with no indication anything is different.

Do I absolutely have to use the .chl file described in the MC2XML docs (http://mc2xml.110mb.com) to limit which channels are downloaded from each source, to keep things tidy so that each channel only appears in one XML file or the other, and enable only the matching channels in each capture source, to avoid confusion between the two? Meaning I can’t let both EPG sources contain ALL of its channels which led to my original question if the latter were allowed how would the TV guide know which EPG source to use for the same tuner?

I'm pretty sure it will use both EPGs and overlay them. That's what it did on my machine. I was able to choose the program entry from EPG source 1 when moving to the right through the guide, and the program entry from EPG source 2 when moving through the guide to the left. Honestly it was a mess, and sub said don't do that, so I restricted my channels with MC2XML's -c option.

[eramos581]

Ok. If those are the rules then I will make sure to follow them.
Based on this it seems the only way to keep two EPG sources for one tuner where both contain their entire EPG channels database would be to keep two seperate copies of the "config.xml" and "gbpvr.db3" files one set of files per each of your EPG source configuration per your one tuner. Is this correct?

Thanks for your responses.
