Live TV works - recordings won't play

[sub]

Just to confirm - I also downloaded the sample file, and it's full of continuity and TEI errors. You're definitely having signal errors at that HDHR.

When you use live tv vs recording, it starts at the opposite end of the device list, which explains why live tv works, but recordings don't.

Also log messages from one vs the other:

2022-03-10 18:51:36.876 [DEBUG][4] locked=1, present=1, strength=100, quality=84 (took 1937ms to check)

vs

2022-03-10 17:32:02.972 [DEBUG][7] locked=1, present=1, strength=99, quality=31 (took 1187ms to check)

(The 'quality' is not stellar on either, but that second one is particularly bad)
