I would like to transfer and authoring my digital home video to my DVD-R Pioneer A05 in Ulead Workshop 1.3

Which is the best settings ( I mean video bit rate, audio, and so on ...) to check in Project Settings to get the best quality on DVD ? I know I can go with the High Quality , but maybe there are more settings that I can check.

Which is the maximum lenght of the movie (in time) from my digital Sony camcorder to be able to capture in my Pentium 2.4 Ghz computer to fit later on in 4.7 Gb DVD-R ?

Thank you very much
