VCD is generally poorer quality then DVD and is used by bootleggers so they can sell off there pirated movies on 2 Standard CD?s rather then 1 DVD disk ( the streets of china are a classic example ) ? Most DVD players can read these CD-R?s with the VCD movies on them, Because they are in the raw Mpeg format. This means DVD players hooked up to your TV do not hafta do any decripting or decoding to play the file.
AVI is the better of the two formats but it is allot newer and requires decoding only a select few DVD players will run .AVI format video ie: Kiss DVD player does I don?t know of any others
But of course PC?s Will run any format so long as you have the required Codac?s
Xvid, DivX,
