Error message -2 and -12345

Question

Hello out there,
I've seen other people ask about these error messages on encoding with DVDSP4 but never seen a satisfactory answer.
On the record: does anyone know what these error messages mean, and even more importantly, how does one resolve the issue?
for my specific background info, see my post about the DV PAL QT file not encoding from earlier today.
and thanks to everyone who posts and answers in this forum.

With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)
