DVD Shrink 3.2 Vista permissions problem

I had DVD Shrink 3.2 working on Vista earlier - the first couple of installs on Vista Ultimate worked good. I had it working on my Vista Business computer, but at some point it stopped working properly.

DVD Shrink would launch, and pull up a list of discs, but when I selected my physical DVD drive Z: it would come up with an error:

DVD Shrink encountered an error and cannot continue.
Failed to open file "\\.\Z:"
Access is denied.

At first glance it looks like a permissions issue, as the navigation is via directory traversal so as a non-administrator you can't get to \\.\

I think the source of this was since I had installed DVD Shrink, I had changed my drive letter from D: to Z: and have also installed Virtual Clone Drive which installed virtual drive letters. An uninstall and reinstall of DVD Shrink 3.2.0.15 (last known build) didn't fix the issue.

Other things that didn't work - running SysInternals ProcMon didn't show any access denied errors. Running the application in Windows XP SP2 compatibility mode did not work either.

What does work - running Compatibility mode / Privilege Level / Run this program as an administrator. For now I'll be using this way until I can reproduce the cause.

PPC-6700 registry

Just having had to reinstall a few applications on my PPC-6700, the one that became essential was PHM Registry Editor. Really, who doesn't build a registry editor into an OS? Note to self - check back with Windows Mobile 6.

The one to use for the PPC-6700 is PHM Registry Editor and use the regedit.Mrln_ARM.CAB build. Copy the CAB to a temp folder on the PDA and install from there.
