This will be is one of the best reviews I ever wrote.
The really cheap App is excellent for converting (and combining) video, probably the best I know for Mac. I have to do different tasks like that professionally for five years know and do know most Apps out there for Mac. Finally I tried VisualHub and I am so very happy. It renders some of my former complex tasks in a time saving one-step-operation.
It combines hundereds of files to one other video or directly to DVD (Toast Titanium for example does a Maximum of 99). It automatically sorts the files even if they are hex-numbered!
It runs stable and - one of the best things in my eyes lets you work your other work flawlessly, for it has a "nice App" option. If clicked it uses only really unused Computer Power. No stumbling of the Computer, while processing ansd working other tasks, even on a G4 Dual 450Hz.
Also possibility to use Xgrid-Power, but I haven't tried that yet.

Picture support (like JPEG) would be nice for me too, but this is another thing, so absolutely no flaw of the App.
Thank you so much for that work!
