You have two choices for (strictly) over the air programming. The  
first one is exactly like you thought it would work:
1. Use your converter box and current analog capture device. Tell myth  
to tune the analog capture card to channel 3 and tell mythtv to change  
the channel on the DTV box. This will require an IR blaster to send  
the correct commands to the DTV box. This is assuming you have a DTV  
box with known remote control that lirc can control.

2. Replace your analog capture card with a digital one and let mythtv  
tune the card to the correct channel. I only have expensive digital  
capture cards ($129 for my pcHDTV-5500 and $170 for an HDHomeRun with  
2 tuners), so I don't know how well the cheaper ones work but I know  
there are cheaper ones.
