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.
