The channel lineup has not changed, and nothing has changed on DRM that I am aware of. If it had, I'm sure that all of the foxsports channels would have been affected. Also, the missing channels are all over the place and were previously working, and some were even recording (i.e.232, 300, 301, 425, 427, 553, 571, etc... very random).
Up until today I was running v 22.0.21 and I updated to 22.0.28 to try and troubleshoot the issue. I don't know what version I was running prior to 22.0.21 or whether it has ever run properly on that version. It's not something that I kept track of because I was having no issues.
I have attached 2 logs, the earlier log was tuning to 583 (failed) and the one a couple of minutes later was tuning to 584 (success) after a log reset.
