HDTV to DVD isn't 16:9

[sambat]

The source is a transport stream file that DGIndex says has an aspect ratio of 16:9
Using FitCD and encoding from the AVS file in DVD Flick, I get a DVD that GSpot says is 4:3.
DVD Flick reports the source as 4:3
I was expecting that the output would fit the widescreen TV without changing the picture size on the screen.
Assuming that FitCd and DVD Flick know what's what, can someone correct my understanding?

It is letterboxed, black borders and 4:3. Convert instead to 720x480 and with 16:9 flag(if you can set it in dvd flick).

And if it was 16:9 you should have checked the Anamorphic box in the Destination properties.

Thank you both for the suggestions.
If I check Anamorphic for the output in FitCD and set DVD Flick 'Target Aspect Ratio' to 16:9 , then Gspot indicates it is 16:9, but the result is pillarboxed on the TV (no bars on top or bottom).

I't looks OK for content. It needs the 16:9 flag.
