I recorded a video of the iTunes DSM in action. I'm planning on posting it to YouTube to show how to use the program. In my testing, the program seems to be solid and ready for use.
I did use iTunes DSM on my own personal library finally and am pleased with the result. It's also convenient in that you can use the program on the other computers in the house and fix the orphaned files in the iTunes databases!
When I post the YouTube video I'll post it on here as well. I am still trying to figure out if I can host the program here on blogspot. I haven't really seen a way to do it yet.
