FYI: Good sotware for archiving your own DVDs is DVD Shrink (freeware). You can automatically chose which features you want and which menus you want from the disc, then it automatically degrades the video a little bit (completely unnoticable on non HD TVs) to get it below 4.7 GB (one single layered disc size).
I have a habit of treating my discs like dirt (leaving them out int he open and never putting them away). So, archiving is a must for me, otherwise, my DVDs wouldn't even last a year.
Note: If you are archiving for the far future, everything eventually will be going to HD. So, a degraded video (due to DVD shrink) will look like crumb compared to its original DVD. But, for now, there is no difference on analog TVs.
