Hi
I see two problems
• Memorex never worked OK on Mac when doing Video-DVDs - I only use Verbatim (more organic dye in them)
• Size in Gbs - iDVD doesn't care about Gbs at all only duration. And Duration is the sum of Movie time AND MENU TIME.
I have 500Mb files that are to large to fit and 50Gb files that fit's nicely.
iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
Menu can take 15 minutes or even more - I use a very simple one with no audio or animation like ”Brushed Metal” in old Themes.
About double on DL DVDs.
Yours Bengt W
