So... I received my mini today. Setup went smoothly on this old 4:3 RCA Proscan SDTV (480i) via the Tivo composite breakout cable. Then I noticed the HD menus were squished and so was ALL HD content I was viewing (though downconverted). I was disappointed to find no Aspect Ratio options in the Video settings menu. I made sure the only resolution I picked was 480i, to no avail. My older Series3 I used to use on this TV had the benefit of being able to view any HD content from my other Tivo's and would properly letterbox any 16:9 content on the 4:3 display. This mini? Not so much. I can find no documentation that says they don't support 4:3 TV's. Not to mention, they advertise and sell the composite breakout cable for 480i. Anyone have a similar experience or know anything about this?
