Is it possible to put 2 movies on 1 DVD9 (ex.shrek 1 and shrek 2 already size with dvdshrink on DVD9) I see that some dvds out there have 2 separate movies with there own menu. How can I do that.
You can use Re-author' mode in Shrink.
Select a DL in preferences
The browser menu on the left side lets you locate the folder containing 'title 1' of the first video.
Drag that to the right panel.Same for the next video, drag 'title 1'.
I haven't tried it but I heard that DVD Decrypter is best for burning these disks.
If you want a menu, try TMPGEnc DVD Author (there is a guide on Afterdawn).
if you want to retain all the menus, use dvdremake to merge the two folders. you can merge up to 4 folders.
for a much better result I would rip the original dvds and then remove unwanted material such as previews with remake and then merge them also using remake. then run it through dvd-rb/cce DL mode if compression is necessary or if your not that particular you could use DVD Shrink or similiar transcoding utility.
