Hi, Brad -

Thanks for the responses.

And I'd like to apologize for being so vague, as I'm not sure exactly on 
the terms involved and all that good stuff.  I'm pretty new to MythTV, 
so I'm sure I'll get the hang of it soon :)

"Some other content" would be described as a video on disk that's just 
in repeat mode or something like that.  I think I've read that I can do 
an overlay like that, adding some transparency, but eventually I'd want 
to get down and dirty and actually re-size the video to the point where 
a transparent overlay isn't needed.

Does that help?

Thanks!
