DVR - Comcast Scotts Valley Fox Channels 3 and 702 - wrong HD indication on channel 3

So I think something screwy is going on with the Santa Cruz/Scotts Valley Comcast signal. As you can see here, the Hauppauge card seems to think channel 3 is HD (but it’s not)

702 is still the HD channel, but Plex won’t auto-select it or save that manual assignment from the DVR setup screen. (see the video from my previous post) What DID work was using the channel 3 guide on 702.

For some reason it’s happy to save that mapping. Programming is the same, so that works fine for me, but something odd is still going here.

BTW: I manually unchecked all the non-HD channels. Easy once you figure out that Tab & Space work for move and select.
