This is the first time i have tried to make back-up dvd's of movies, as the kids have nearly destroyed their range of films, so excuse me if this sounds obvious -
I used DVD shrink to reauthor my DVD, then imgburn to burn it. It worked fine, but the length of the film is 2hr 43mins, and it burned the whole thing onto one blank dvd(which is supposed to fit 2hrs max). The green bar(which indicates amount of space spare) on dvd shrink was not to the max, and the green bar on img burn was at 96%. I thought the picture may have lost a bit of quality, would this be the case?
Could be totally wrong but ImgBurn is showing the amount of disc used and DVD Shrink should show the quality. There will be some quality loss at anything under 100% in DVD Shrink but you should be able to put about 3 hour's on a regular DVD (DVD 5) and, it's personal preference, but a quality reading of 75%-80% should be ok; at 96%, I doubt a person could see a difference.

Yes. DVD Shrink works great at anything > 90%, as was noted you had to be at about 75%.
You could reauthor (movie only) in DVD Shrink and save uncompressed, then run that through the free DVD Rebuilder and re-encode with the included HCenc encoder. That would give you the best SL copy. Otherwise read up on burning it to a DL disc with ImgBurn.
