[mythtv-users] duplicate recordings, new card

[Gareth Glaccum]

Ok, I am being naughty, I am running slightly different versions of myth, 
hopefully this is not the issue (given that scheduling only occurs on one 
machine, I doubt it, however, the scheduler is the older version). I have 
had a quick search for duplicates etc. through the list, but didn't really 
see anything which matches my problem.

I have recently added the slave backend, with a DVB-S card (Hauppauge 
HVR-4000 type). My master backend has 3 DVB-T tuners, all identical.
Before the upgrade to having a slave backend, the 3 DVB tuners were under 
one listing source. I didn't really have problems with duplicates. I use EIT 
for DVB-T
I want to use EIT for the DVB-S, so I set up a second listing source. The 
problem is, that I am getting masses of duplicates. There are several ITV 
channels (which I should prune down, but it makes for a good test of 
duplicates). One example is copied below (actually, a bad example, the 
program id is /NaBB and fp.bbc.co.uk/NaBB). But there was at least more than 
one which did match.
