How do I get 16:9 DVD video to play correctly on my 4:3 (regular) TV?

When I use "DVDFlick" to encode a video to DVD how do make sure the "widescreen" format not only encodes on the DVD, but plays on my regular TV as "letterbox" (16:9). What been happening is I get the wide screen format on the DVD, but it plays on the TV all scrunched horizontally. Sometimes It works correctly and I get black top and bottom on the picture presented in wide screen format, but I don't know how that happened. Is there a box I need to check on the DVDFlick input to insure I don't lose the wide screen information on the DVD, but also that it plays correctly on the TV?

When converting AVI files with this program unless I 'Edit Title' (right side of pane) and under 'General', set 'Target Aspect Ratio' to 'Widescreen' and also under 'Video Sources' set 'Pixel aspect ratio' to 16:9, the AR gets screwed up.
