Embedding an movie viewer into a gtk window

["Amadeus W.M." <amadeus84 verizon net>]

Suppose I wanted to write a gtkmm front end (with some knobs and 
controls) for a viewing application like tvtime or xawtv. How would I go 
about embedding tvtime into a gtkmm window? I mean, what do I do on the 
gtkmm side? 

The reason I have to have tvtime running into a gtkmm window is because 
the application I'm developing is for a pan-tilt-zoom camera and I want 
to be able to click on an object in the tvtime window and have the camera 
point to that object. That is, my application must read mouse coordinates 
in the tvtime window, translate them into (pan,tilt) and send the 
appropriate command to the camera. Tvtime does not read mouse 
coordinates, so that's why I want to put it inside a gtkmm window that 
does.

I already wrote a simple gtkmm application that can move the camera 
(using sliders) to a desired position. I can run this at the same time 
with tvtime, but I want to be able to take mouse coordinates from tvtime 
and translate them to (pan,tilt). 

Thanks!
