I am running Windows 7 Home Premium Edition, kept very up-to-date with the latest Win7 patches.

Before I run Windows DVD Maker, I always insert a brand-new, blank DL (8.5 GB) DVD into my DVD (Drive G:)

Then I run Windows DVD Maker, the bottom left always says "0 of 150 minutes" to begin with.

WHY?

Because of this, I cannot fit several files (4) which total less than 7 GB because Windows DVD Maker already says "will not fit".

WHY?

Many blog "experts" say to select the "right drive capacity" of "DL/9 GB" at the bottom of the screen.

WHERE?  There is no such thing.

Please help.
