Plex DVR Channel Guide missing a lot (Cable)

Version 1.14.1.5487

I have an HD Homerun Prime with cable card (Comcast) and all that is working great.
My issue, i have about 593 channels available, 505 are usable (rest are DRM that i don’t care about) However if i use the Built in Plex Channel guide, we only get about 420 Channels matched up. I was able to get 503 using zap2xml and using tvguide.com’s listing.
I don’t really like using the zap2xml, it doesn’t seem to work as well (Slow), and i would prefer to use Plex’s built in listing.

Is there a way to get this channel guide updated to include the missing items, or are they hard linked to another service? I noticed Zap2it’s listing is similar in that its missing a lot of channels.

I Figured out the issue. So the Guide from Plex wasn’t originally including channels 1000+. Turns out Comcast has been adding new channels in the 1000+ range, and several are duplicates.

Now that i’ve deleted and recreated my DVR, using the built in Guide is working perfectly. Its seeing all channels 0-1999. It also auto removes duplicated channels (800 HD is ignored over the preferred 1800 HD)

Not sure why it wasn’t loading them last week, but all is well now.
