I ran into something like that playing with QAM signals. The buffer
took forever to fill. Turned out to be digital music channels with a
picture that changed only when the song did.
Even a MD system still would not tell you if you had the "wrong" show
due to lineup changes etc. I don't think there's a substitute for a
sentient being checking the recording, or at least a Linux user.
The industry runs into this all the time. Some person has to sign the
"affidavit of service" certifying that a given commercial actually
did play. There have been all sorts of attempts to automate this
process, but I'd never sign a legal document saying it ran unless I
or somebody I trusted had actually seen it.
