PlexTV Server can no longer see HDHomerun tuner

Many of those URL’s are not available on the older HDHomeRun models.

I get 404’s on all but the first with my older HDHR (which I actually have working, but I downgraded ages ago)

For the lineup, I use http://ipv4-api.hdhomerun.com/api/lineup?DeviceAuth=xxxxx, where the DeviceAuth is defined in the response from discover.json
