how to 1:1 DVD Copy, but main video downsampled?

hi! i'm new here. i've now tried for an hour to find something in this forum but no luck :( my situation: i have here some dvds which i'd like to copy. each is ~8gb big. each dvd has 4 episodes, which i already encoded to 1gb (880mb video + 120mb audio) each. my problem: now i want a 1:1 copy, including all menus, subs, audio stream and extras with the 4 episodes which i downsampled. is there an easy way to to that? is there any way to do that? greetz piece

Well... 

Hard to believe you did a search about it. Anyway, use the DVD-9 to DVD5 full backup guide from Trilight, or his brand new "flowchart-based" guide. Process is not that complicated if you take your time and go slow. Good luck. Waldok :cool:

the dvd9->dvd5 guide was without menus as far as i've seen. and the thread from trilight wasn't yesterday here :-( i'm already in the middle of it.
