@anon18523487 – would you be able to take a look at this issue as well? This has also been an issue in Plex web for me for several months:
As stated in title, switching the filter to “HD Channels Only” does not filter out all SD channels. In the example screenshots below, channel 002 is an SD channel, and should be filtered out when “HD Channels Only” is selected. I cannot tell if this issue only applies to SD channels that have an equivalent HD channel. The overall channel count does change, but not all non-HD channels are getting filtered out.
