Assigning correct Logical Channel Number (LCN) to each channel after scanning

[martinu]

When I scan for all multiplexes and all channels within those multiplexes, the list of channels seems to be in a random order (I think it may be random within the order in which multiplexes are found, ie with the mux that has the lowest UHF frequency first in the list). The well-known Logical Channel Number (LCN) for each channel does not seem to be used. Is there an easy way to tell the scanning process (either during scanning or afterwards) to assign the correct LCN (eg 1=BBC One, 2=BBC Two, 3=ITV1, 101=BBC One HD etc). I realise that I could go through and manually renumber the channels (Settings | Channels | double-click on channel | change first field in General) but this is a bit tedious; also it may get screwed up if I re-scan in the future.

Given that digital TVs and PVRs, and PC software such as Windows Media Centre, use LCNs as a way to go quickly to a channel, those LCNs are well-known so it seems a good idea if NextPVR could use them :-)

I've only tested with DVB-T (terrestrial transmission) but the same concept exists for satellite (eg Sky)

See https://en.wikipedia.org/wiki/List_of_DT...ed_Kingdom for a list of LCNs.

It does try to use the LCN values from the broadcasts, but due to a slight difference in the UK timing it sometimes finds the channels and moves on to the next frequency before it finds the LCNs. It seems to be worse on tuners that take longer to tune a new frequency. You could try increasing the <ScanDropTime> setting in config.xml to see you can get a reliable time.
