I am very new at this and I'm not even really sure how to word this. I've got the basics down so far. My question is about compression and quality loss. Sorry if this is a dumb question. Is it better to always re-author and just do the movie file only? Or do you leave a lot of the extra content in and allow it to be more compressed? How much quality loss will there be - a lot of quality loss, a little loss? How do you more experienced people choose to do it? Let me know. I don't want to make a bunch of bad quality discs right from the start. I'd rather ask you first. Thanks!

Hi, welcome.
You pose a great question, and I am sure you will get lots of differing opinions. I have compressed down to about 48% and did not notice a difference on my TV's. I do not have big screens though so that may make a difference.
I only do the main movie backup cause I don't need all the other stuff that filmmakers put on them these days. That helps with the compression levels.
Cheers.

@KimTx,
There is no substitute for 100% as far as quality goes. I always try to keep my back-ups at 100%. That is, I only copy Movie Only to a DVD-5 and if I just Have To Have the full movie with menus, extras, Etc, then I copy to a DL DVD-9.
The way I usually explain it is: Computer files, like movies, are made up of 1?s and 0?s with no space between them to compress. You can compress a 10lb. marshmallow to fit into a 5lb. bag by squeezing the air out of it, but you can?t squeeze a 10lb. bowling ball enough to fit that 5lb. bag. You have to chip and cut it to size. Thereby loosing the quality of it and no matter how much you analyze it you can never recover the quality?.
Think about it, and then decide for yourself. Are you willing to give up Quality to be able to put a large movie on a half size disc.
Happy Burning..
You beat me to the draw, again Rugger LOL

yeah, but you gave a better answer!
For the most part, most DVD9's that I compress usually end up about 78 to 100% which is very palpable for me anyway. I can't see any quality loss on my TV screens.
Cheers.

He He, I very seldom save anything to DVD-5 that?s below 90%. But when I do I always use the AEC in Shrink set to Maximum Smooth??..
I know, that takes a long time, but it?s worth it..

LOTR trilogy had the most compression for movies that I've tried yet, I think 65 - 70% if I remember right. With the AEC on as 2oldgeek stated, copies were flawless and I use my 51" theaterwide TV as test standard.

@Deadrum,
I did all 3 of the LOTR, 2 disc extended versions and used AEC extra smooth. That was a trip but worth it?..
The reason was I didn?t have enough DL discs and wasn?t about to pay what they wanted here locally LOL
