Query about the "Volume don't exceed" setting in DVDx

[tickfree]

I saw in "Sefy's Ultimate Newbie DVD Conversion Guide v1.9" (GREAT guide btw, tnx ALOT Sefy) that the volume he created was 798.1 Mb and 1:18:12 long and got confused. What is the value I should pay attention to?!

I just copied my first DVD and I'm about to encode it using DVDx. However, the volumes I get are 1.5 GB large and 1:10:00 long... So u see my query?! When should I go by running time per volume, and when should I go by MB per volume?! OR should I ALWAYS go by either one or the other?

Help needed.

Go by the size, the size he chose was that of the size of his cdr's the size he chose was on an older version of dvdx, if you custom size on the new version it will convert your whole movie into segments of the size you choose.
So if you have 800mb cds choose 798mb that way you will get an 798mb and a 702mb movie fitting nicely onto 2 cds, also when he chose his by segments it was so when the cd stops, it would stop at the end of a scene and not half way through some action.:D
