Video clips film in AVI format 650MB not playing on DVD player

it is a problem of codec, or you have an illegal os.

the codec is the problem

However, if you mean a real DVD player that sits with your TV (as opposed to a program on your computer) then I'm afraid most DVD players don't like AVI files, the much prefer VOB, which is the standard DVD file.

To add to what toinbach says, AVI is a data file CD format, not DVD. There are players that automatically detect the difference and work with either format. If yours works only on DVD format however, it will not play an AVI file or any of the CD Data videos like MPeg or Wmv.

You can record CD DATA files on a DATA DVD but they won't play on a DVD player unless it reads both DVD and CD Data formats. I know that sounds confusing but don't blame me, the computer industry is still evolving.
