Problems Converting DVD to MP4

Hi all,

I’m trying to convert my DVD’s to MP4 format and am having some problems. I am using Xilisoft 4.0 and it converts most of my older DVD’s but some of my newer DVD’s like the LoTR moves, don’t convert. When i try to watch them i get a message “Error 2048: the file is not a movie file” which i assume is due to the DRM that’s on the DVD. I’ve tried using DVD Decrypter to decrypt and remove the DRM so i could convert the files but in most cases i get the same problem. I assume DVD Decrypter is just not able to remove some of the newer DRM.

Has anyone had this problem before? and if so were you able to find a solution, and how?

Thanks in advance. Any help would be appreciated.
