What kind of DVD plays IN-PROPORTION on both widescreen and regular TV's?

Question

They have a lot of different codes and i HATE when a widescreen DVD smushes up into a narrow version on my regular TV.

Ideally i'd like one that plays widescreen ON my regular tv with black bars above and below the picture.

Thanks!!!

The link below provides a fairly simple explanation of the issues and probably answers your question.

Answer 2

There are DVDs that on side A have a 4:3 version and on Side B have a 16:9 version.
Any movie, created on a ratio larger than 4:3 (1:1.33) , when viewed on a 4: 3 screen will have by default black bars above and below the picture.
