Unless you have a multipurpose DVD player, meaning,,,,,it can play MPEG AVI, DIVX, and the sort, it won't play the CD or DVD if you drag and drop the file directly to the CD or DVD...
You have to use a conversion DVD burning software to play in your DVD player
I use Sonic DVD.
Here's what happens...
Movie XYX is 730 meg,,,,DIVX,
I drop it in SONIC create chapters, blah blah blah,,,,,then click create...
It then goes through a 1 1/2 hour process of converting and transcoding and whatnot, then it takes the newly converted movie, and burns it to the DVD in DVD/R format.....
Now it will work in most average DVD players..
Be warned, this method although conveniant for the average JOE. the conversion makes a 730 meg file end up being 4 or 5 gig!!
The quality is still excellent, but the enormous file size makes it so you sometimes have to have multiple DVD's........
Ok, want to really solve the problem, do a search for DVD players that have chipsets in them and will recognize MPEG AVI DIVX XVID, so forth.........
Now you can take your 730 meg movie and burn them on CD or DVD by plain old drag and drop, and they will 99 percent of the time play fine..........
$60 multi function DVD player
Or the long way like I am doing
It works either way.......
