I have DVD cloner 5.0 and have 3 questions;

1. My mother is a documentary film maker and has 5 58-minute shows on 5 separate D5's.  i would like to put them all on one D9 dual layer disc.  If this is possible, can i also make a menu to select from each of the 5 shows?  Additionally, should i worry about compressing 5 hours onto one D9?

2. i have had trouble copying D9's to D5's and retaining necessary subtitles in the movies.  I can have either permanent subtitles or none atall, but the foreign language snippets that are translated in most of the dvd's do not come out.  I only copy D9's to D5's by customizing the selection and only copying the movie; is there something else i must do?  Additionally, the subtitles are always one when i play these dvd's and i must manually turn them off, is there a way to copy the DVD so the subtitles are automatically off but still accessible?

3. When i have copied D9's slightly over 2 hours to D5's (copying only the movie) i have had troubles with the DVD's skipping and am wondering if it is a compression problem or if i am copying incorrectly.
