Sure, I could totally bypass mythtv and do what you say, but I was kind of
hoping to be able to see the video mostly live and be able to hit record
around the right time (yes, I know about the liveTV delay, which is why I
say "about").

I was hoping there was a supported way of doing this in mythtv, or at least
a simple hack like on a tivo, but if not, oh well...

Thanks,
