4.7 gigs is precisely the capacity of a single-sided DVD (DVD6).
Double-sided DVDs (DVD9) hold twice as much - 9.4GB.
You are correct.
Things I am trying to avoid: Buying a double sided DVD burner and double sided DVDs.
My issue is that the original mpeg file is only 1.6 gigs. why am I not able to burn only a 1.6 gig mpeg file? It always wants to convert it to a 4.7 gig movie file, then the software will produce a dialog box saying there isn't enough space on the DVD.
BTW A.P., I am not interested in buying equipment to add to my TV and DVD player to play mpegs. It already is able to play them. I just need to get them successfully burned to a DVD.
