You are all doing it the hard way. There is a freeware program available now for backing up your DVD's. It's called shrinkdvd.
A normal dvd that you buy at blockbuster has 2 layers of data on it (9.4 Gig). A blank dvd+r or dvd-r has only one layer (4.7 Gig). So you either need to pull some of the data out of the burn (menu's, extra audio channels, subtitles, deleted scenes....) or you need to split it over 2 discs, or... you can recompress it to make everything fit on one disc instead of 2.
Some movies will fit on 1 disc if you burn the movie only. Others will fit menu's, movie, features, everything on just one disc (not many, but I have seen a good many in my collection). But most of the time if you want to make a copy of the whole thing with features, menu's and everthing you will want to recompress.
This program does a very good job of recompressing the move and can do it in as little as 20 minutes. A single pass will take about 20 minutes. A 2 pass analysis will take about an hour or so but with considerably better quality.
Just for the record... I have a 9 foot screen with an LCD projector and yes I can see a small difference when I recompress, but that is on a 9 FOOT SCREEN!!! (Of course I know what to look for. The average user will notice that the copy will be no different from the original unless you are using a HDTV of considerable size...... On my 36 inch TV it looks the same as original.
Even if you watch on a 9 foot screen, the recompress is great quality... very close to the original disc.
You can also choose to rip just the movie and not the features with this program. This way you may not need to recompress. If the movie alone is too big to fit the application will recompress it just a little so that it will fit. (It really is a cool program.)
I have DVDXCOPY Platinum and Express, and Smartripper and DVD-Decrypter and DVD-Fab. I spent more that my share on these items and I still choose ShrinkDVD for all of my latest backups.
Anyway, you can download shrinkdvd from doom9 or just search google for it.
Hey It's free!!! And works great.
Oh yeah, you still need a program to burn the files that it produces (nero, easy-cd, whatever will let you burn dvd-video discs.....your burner probably came with what you will need.
