I just backed up "The Polar Express" R1-NTSC

First, I tried DVD Decrypter, out of habit. As a result, the sizes of the VOB files were less than what was initially reported. When I played the backup on my PC, I got about a little over 3 minutes into it when I was thrown into a clip with scrolling white text on a light blue background, informing me of the evils of theft. Ridiculous! I bought it this morning and just want to back it up.

Next, I tried DVDFab Decrypter 2.9.6.0 and it seems to play fine on my PC.

PROBLEM:

Two decrypted files have a size of 8K. Whereas, DVD Decrypter reported them as being 10K in size, and in fact DVD Decrypter reproduced both files as 10K on my hard drive.

VIDEO_TS.IFO 8K
VIDEO_TS.BUP 8K

Is DVDFabDecrypter reducing these files through optimization, or is it not decrypting them properly? I am tempted to replace the 8K Fab decrypted versions with the 10K ones that DVD Decryptor created but I will wait for some advice before attempting it.

Thanks,

Gary
