I've gradually been ripping my DVD collection to hard drive. Now I'm just copying the VIDEO_TS folder into a folder with the DVD title, but when I started, I was ripping to ISO files. I have a few exercise DVDs with multiple workout routines that are accessed from a menu. When I try to copy the VIDEO_TS folder out of the ISO file (or from the original DVD), the resulting file is much larger than ISO file. For example, I have one DVD that is 8.54 GB in its original form or as an ISO rip. When I copy the VIDEO_TS file out of it, it says, "Now copying 87 GB." I did a web search and found the answer: some DVDs contain multiple references to VOB files and thus make multiple copies of those files. That raises some questions:
Why would anyone do this? My first assumption was that it's to discourage copying by making an annoyingly huge VIDEO_TS folder. However, if you just rip a DVD to an ISO file, there isn't a size increase.
If there's a reason behind it, why is it so rare? Out of ~300 DVDs I've ripped thus far, only three have this issue, and they're all exercise videos.
Finally, is there a way to defeat the multiple-file-reference issue when copying? It's not a big deal, and I ask mostly out of curiosity. My aim was to convert each workout into an MP4 file that I could put on my iPad. Now I just play the ISO copy from my MBP.
