(1) Me a culpa regarding mp3, should have been mpg2.
(2) The sum of the four video clips is 9.73 GB as captured and encoded
into mpg2.
(3) I will try re-capturing the discussion from my camera to PD5 as LP
clips, edit, add titles, chapters and menu and note what the overall
size becomes, then try to burn to DVD.
(4) I posed the question on Cyberlink's Power Director forum 8/14 but
have not yet seen an answer.
Thanks for your suggestions.
