Personal opinion here (and not to take away from Smarty's excellent
response) is that, if the client wants it shot in 16:9 mode, use a
camera capable of doing this natively instead of shooting 4:3 and then
doing a fake 16:9 DVD 9i.e. cropping/letterboxing).

I had the opportunity earlier this year to borrow a friend's camera that
shoots real 16:9 (SD, not HD) to shoot a stage play. All I can is WOW!!
Seeing it on a 42" widescreen TV convinced me that, in the future,if
someone wants me to do widescreen, I'll use his camera again.
