I'm a newb to burning DVDs, i backed up my War of the Worlds DVD and i compressed it with DVD Shrink, the quality of image isn't like the original, its understandable since i'm compressing the DVD and backing it up to another with less capacity but i was wondering if there was any way to fix this?

After you click backup in shrink you can try a different level of copy quality in shrinks settings. Try Max smooth or another offering that is different than the Sharp default settings.

Cheers.

You can?t make a silk purse out of a sow?s ear??..

The way I always explain it is .. You are not compressing the movie; you?re butchering it..
There is no space between 1?s and 0?s, as in the bytes of a movie file, that can be compressed. To make the file smaller, you have to remove some of the 1?s or 0?s, thereby removing Quality.
You are able to compress a 10lb marshmallow to fit in a 5lb bag just by removing the air. Then when the air is put back, you have a 10lb Marshmallow that has lost none of its quality.
You can not however, compress a 10lb bowling ball to fit a 5lb bag without chipping or cutting it in a manner that looses all the integrity of it?s quality. Thereby loosing a part that cannot be replaced, no matter how much analyzing or transcoding you do to it?

The only possible way to get 100% quality from a Back-up of a movie then, is to make a 1 for 1 copy to a double layer disk or do a movie only copy cutting all extra sound tracks and extras to get it as close as possible to 100% to a single layer disc..

Just the thoughts of a really Too Old Geek??.

I did this movie originally with the main movie only and no AEC controls or Deep analysis and burned at 6X. The resulting copy was perfet until 15 minutes from the end, where it proceeded to pause, stutter, and had some pixellation. I then redid the movie using deep analysis and AEC set to maximum smoothness and burned at 4X. The result was a flawless copy with none of the above errors.

I also did this movie and the backup came out very close to the original, which I may add is not that great quality wise to begin with. Spielberg filmed it funny, it looks overly bright and washed out.
