UK-Crystal Palace Updated Frequencies

[oxsxn]

I set up NextPVR last week because I was fed up with the terrible delay with internet streams of TV, which is most annoying during the World Cup and Euros. If you're watching iPlayer (or, god forbid, ITVX) when England are playing, you may as well give up on being surprised by anything because everyone in a bar or watching over satellite/aerial will be approximately 5 days ahead of you.

Now that I have set up nextpvr feeding into dispatcharr, I can watch with between 2-8 seconds of delay (depends on SD or HD)! Perhaps not quite enough for a penalty shootout, but lightyears better than any other internet option. I did find, however, that the included frequency file for my transmitting station - Crystal Palace - is out-of-date, so I thought I might share my updated file here for anyone who needs it (DVB-T2 channels don't work on the npvr included one or the newest one on linuxtv.org because the frequency is incorrect in both, for example).

That's it! Hope at least some people get some use out of this (maybe even for the Norway match in 90 mins)! Oh, and, thank you for this great piece of software - I finally managed to get a use out of my 12-year-old xbox tuner!

The Linux scan files don't come from NextPVR they come from the Linux distro and often these distros are out of date, or users use older distros The reference file has the same thing you show https://git.linuxtv.org/dtv-scan-tables....stalPalace so I typically suggest users go there when they encounter scan issues.

Hi! Yes, I mentioned in the post that the file you linked from linuxtv.org is also out-of-date - there's a couple of frequency differences between it and what I used. I tried using linux-tv.org's latest file and those two channels don't work properly because of the incorrect frequencies, so I had to try finding them with the freeview website and my tv's support settings. Upon doing so, I changed the linux-tv.org file to what I shared, and it has worked since. Anyway, hope you have a great day!

Odd the frequency difference are close enough the they should be able to lock, perhaps it is a tuner issue. It might be worth try a w_scan2 scan and seeing what it finds https://github.com/stefantalpalaru/w_scan2 That is the most reliable way of working about bad scan files.
