I only use LiveTV for testing my tuners, which is why it seems broken to
me that LiveTV tunes differently than recordings. Made my tests using
LiveTV result in a false positive.
Rather than turn on quick tuning for recordings, which I feared might
break something else, I decided to rescan. I discovered that there is a
way to rescan only the affected channel, which saved me a lot of time,
making the rescan option palatable. I knew there was an option for full
scan and minimal updates, but there is also one for rescan selected
transport stream (or something to that effect), which is the one I used.
I think this problem is resolved now.
