Thanks to all those who responded with their suggestions, it was appreciated. I was able to get things working correctly. Not sure which of the following two it was, but I would bet on the DEP settings in Windows Vista. The only things I did was install the latest version (3.1.1.2) and follow the below instructions to add
DVD Fab to the DEP exception list, the program has performed great since then.
Could not have done it without the great advice that was given. Thanks again. Here are the instructions again for anyone else who may need them in case they are having a problem.
Thanks for looking into this so quickly Fengtao. You are totally correct that there is no other user solution besides disabling DEP but luckily that is very easy. I think this will start cropping up more frequently as Vista becomes more popular and as more people hear about DEP and turn it on. I will provide instructions here on how to disable DEP for DVDFab Platinum in case anyone else has this problem in the future.
1. Open the control panel and double-click the "System" icon
2. Click the "Advanced system settings" link on the left panel
3. Click the "Settings..." button in the "Performance" section of that page
4. Click the "Data Execution Prevention" tab on the resulting dialog
5. If you are having this problem, the option for "Turn on DEP for all programs and services except those I select" will be selected. Leave it on.
6. Click the "Add..." button below the list box (it will probably be empty).
7. Use the "Look in:" drop-down list to navigate to C:\Progam Files (x86)
* (If you've installed Vista somewhere else besides C:, look there :-)
8. Select the product directory - currently "DVDFab Platinum 3"
9. Select the product executable - currently "DVDFabPlatinum.exe"
10. Click the "Open" button
11. You will see DVDFab in the list with a selected check box next to it.
12. Click "OK" on the remaining open dialogs and you are all set.
You should be able to run DVDFab Platinum on Vista 64 after this point (if not, then you have a different problem). The nice part about this approach is that DEP is left active for everything else.
Let me know if you run into any problems related to this... - D
