Why can't I play a .vob from a CD?

I am curious as to why a .vob file is not played on a DVD player from a
regular CD. The obvious anwer is economics. But is there an underlying,
technical reason why the DVD and CD (oxymoron?) formats are so different?

The file structure is exactly the same as a high density CD (DVD). But the
player ignorantly looks for MP3 files. I understand the "format"
difference, but who should care? We're talking files here. Perhaps my
player is too old (3 years)?

Maybe the player might simply be stupid (feature) in not knowing what to do
with the .vob file if found on a "CD", but it surely knows what to do when
it finds it on a DVD! Perhaps data and media DVD (authored) formats are
designed to prevent something bad happening?

When I drop that same exact file (from CD) into PowerDVD on a PC it starts
playing just fine.

Will consumer stand-alone CD/DVD players ever be smart enough to play
whatever is found on the media?

vob files are not the only files found on dvds, you know.

theyak

it can

check out miniDVD, not many dvd players can play miniDVD's

miniDVD is basicly a DVD but on a CD-R(W) instead of a DVD disc. miniDVD is
also sometimes called cDVD. A miniDVD does only fit about 15 minutes video
on a 650 MB CD-R(W).
