Suddenly can't watch Tuner-based LiveTV. No Guide

[cyberwar_hotmail_com]

Server Version#: PlexMediaServerTV 1.21.0.3711-b509cc236_amd64
Player Version#: (Browser-based)
Tuner Make/Model: Hauppauge WinTV
Guide/Lineup name: n/a
Using XMLTV?: ?
Channel number/Name: all

After working fine for months, suddenly, I can’t get a Guide to watch Live TV.

I bookmarked the “Plex TV Guide/LiveTV” (localhost) so I can watch my tuner from Firefox. When I bring up the link, I get:

The Guide is empty

Please verify your channel mappings and refresh the Guide

Go to DVR Settings

(The third being a link to my devices and a “Refresh” link.) Refreshing the Guide (which goes quicker than normal) simply leaves me at the same message. I’ve tried adding a new (same) device. It goes through a scan, finds over 120 channels, then I’m back to where I was with no Guide and no TV.

I have no idea what’s wrong. Help! TIA.

Did you scrap your DVR and recreated it at the end of last year?
If not, read Live TV EPG - The update you’ve been waiting for

Thanks. Deleting the DVR and doing a full rescan got it working again.

This also allowed me to “uncheck” channels I don’t watch from my Guide Listings that I failed to do when I initially setup my tuner last year.

Thanks.
