hello, i am a videographer and i have just finished a wedding for customers. I have edited in adobe premiere pro 1.5 and i have been using Nero quick start 6.0 for the dvd authoring and encoding. i have a dvd burner sony dru 800A and so far it has performed okay. i go to burin discs and sometimes they have gone through fine but past couple of times there have been places during the wedding that keep freezing and make it beyond watchable. now is it the encoding or the burning proces that is doing this? any assistance would be greatly appreciated.
