Would be nice if you allowed cce to be used with clonedvd, that way users could do 6-pass, 10-pass etc on their dvds and have much better quality dvd5 movies as a 3hr movie done with clonedvd is poor but 10-pass if relatively ok. Default option is to use clonedvd's engine but allowing user to use cce if they have it installed would be nice as i'm sure alot of people would like to leave their pc re-encode the dvd for 1hr or so and have a much better quality dvd5.
