Outputting video clips & DVDs to TV question.

[antdude]

Is it normal for video clips & DVDs to be cropped off (the sides)? My monitor shows the whole picture whether it is wide screen or not. The TV doesn't. I have a Sharp TV connected to my Matrox G400 32 MB (non-MAX) (20"?).

I have messed with the DualHead settings in display properties, but I have no luck! Thank you in advance for replies.
