An update.  I have been working away, installing things like 
gconf-editor and adobereader.  And for the heck of it, I tried the video 
again.  Well it is rolling through the modes now.  Internal only is 
1024x768. both is 1024x768 on the internal and an unreadable external 
seemingly at 800x600 with 1024x768 feed. External only is 800x600.  I 
can't figure out how to set external to 1024x768.
