Hi All:
Been using DVD Shrink by itself, with DVD Fab, Ripit4me, DVD Decrypter, Menu Shrink,etc.
Lately, I've been seeing some movies after compression (automatic and custom ratio that won't fit on a 4.7gb disc leaving me with the re-author mode option instead of my preferred full backup mode.
How can I gain more compression and still use full backup?

Well, I use AnyDVD and 1 Click DVD Pro and have yet to have a problem with any movie. Ever since I changed the setting to auto update, I have not had anything come my way that I can not back up.
Some time ago, I did try an program called ImTOO DVD Ripper, but that was before I went to auto updates, and it seemed to work very well. (can't remember where I found it tho)....
Sorry I can't be of more help, just letting you know that with the two I use I have yet to have a problem. If it works, don't fix it, if it don't work, replace it....

Thanks for your input Mousertm, but all of the freeware programs I've listed have been able to handle any movie to date.
I think that DVD Shrink has some other tools to add more compression and still use full backup with which I'm not familiar.

You can try 'deep analysis' before shrinking then run the 'shrinked' output files through once more.

...well; DVD-RB stands for DVD Rebuilder; it's a program which is unlike DVD Shrink...instead of 'taking out' parts of the movie to compress the video; DVD Rebuilder takes the whole movie and completely 'rebuilds' or encodes the whole dvd all over again.....except with DVD Shrink; it just takes negligible amounts of the video/spec. features that you don't notice and puts them towards more demanding bit rate scenes.....
....DVD Shrink is wat's known as a transcoder.....
...DVD Rebuilder is an encoder.....
...and DVD Rebuilder does a much better job on quality of compression on a full disc backup than Shrink....
..but I will warn that DVD-RB is a lot more time - consuming....
..but if quality is your aim; and you don't mind taking a lil' more time w/ each movie; then this is your choice:)....
...@ least; it works good for me...
...just do a google search on it and you'll be able to read up on it's full potential.....pretty amazing program if you ask me;); one of it's own kind:)

Just to clarify what Halen5150 is talking about a little, the process of compressing a DVD to a smaller size is always transcoding. Programs like DVD Shrink do what's known as 'Compressed Domain Transcoding' which means they just remove data from the existing video stream. Re-encoding, on the other hand, involves making brand new calculations for encoding the video with a lower bitrate. Since you can use an encoder that's basically equivalent to what was used to encode the original you can get a lot better quality from re-encoding than compressed domain encoding. It typically takes quite a bit longer, but IMO it's well worth the time.
We have a guide here for DVD-RB, but it's for an ancient version. Some time soon I hope to get it updated.

I knew about the transcoding and the encoding but am a babe in the woods about the rest of the information, which by the way, I find extremely helpful.
Thanks
