I'd say that's a pretty good bet considering it's popping up on a
network affiliate during a primetime show and I'm pretty sure they
haven't started charging for that yet. :) Now the question is: was Myth
ignoring this until fairly recently, or did they just fubar their
transmission recently? I ask because I recorded from this channel
exactly 1 week ago, but in that time I also jumped about a month forward
in my version of myth.

In the meantime I'm just going to patch my local tree to ignore system
id 0 until we figure it out for sure.
