1080i just as many lines of resolution to the screen per frame as 540p. Both 
send 540 lines, they are electronically identical. You're not throwing 
anything away when you follow Doug's instructions. 1920x540p using bob deint 
outputs essentially the same information to your screen as 1920x1080i, no 
deint. For whatever reason, it works better for some folks. (Me, I output at 
1920x1080i with kernel deint).

I don't think most TVs are 720 lines.
