Have a Hauppauge wintv hvr 955q hooked up to ubuntu server running plex. everything is good except i cant get it working with my current needs. At the time i need to use my cable box still until i can get a cablecard and device for it. So it will output on the cable box’s coax output, which works fine when i hook the 955q to my windows machine. In plex though it requires a channel scan which does not pick up the channel 3 that the cable box is sending out on. In windows i simply skip a scan on the wintv app and it will allow me to manually add channel 3, and then it displays the live tv correctly.
tl;dr … can you skip the channel scan in plex, and manually add a single channel? or other methods to get this to work correctly.
