pretty simple question

i hope? I have excellent luck with Shrink and DVD, but was wondering is there a good way to either compress those files even more to place a bunch of videos onto one dvd for true backup purposes not for play back, so you don't have to re shrink the DVD. So if both the original and backup get destroyed. Kid already destroyed one back up. little pests but didn't know if that was at all possibly or if quality would be lost. thanks all and really appreciate all previous help.

More compression of videos, regardless of purpose, will result in reduced video quality...
