The title I have an issue with is The West Wing Season Six - the same problem on all discs in the season. It's region 2 UK, and it doesn't having any particularly interesting copy protection on it at all.
The AnyDVD (6.1.7.3) status window looks like this:

As i've said before, this disc works fine in my XP machine. I've tried a few other movie discs (Fight Club UK Region 2 is one that I can remember trying) in this Vista Home Premium machine and they worked fine.
The error window I get immediately I attempt to open the Video_TS folder from one of the discs that I have issues with is this:
As you can see from the image, CloneDVD mobile has not loaded the disc - this error comes up immediately the enter key is pressed after entering the Video_TS folder location.
Clicking "View problem details" gives this information:

As a further point, this disc opens and processes perfectly with CloneDVD2. This issue is only with CloneDVD mobile.
I've tried using both the AnyDVD ripper, and DVDDecrypter and opening the Video_TS folder from the hard drive. This results in exactly the same problem as I have described.

I hope this is enough information for a solution to be found but I can easily try more things/provide more info as required.
Thanks for all the help and suggestions thus far.
