Look at your calendar, it's 2009, the Video Toaster has evolved through 3 generations since it last ran in an Amiga. VT5 uses the CPUs in your computer extensively. The SAM is a glorified Mobile Phone, it doesn't have the power to run a VT5 even if the software was there.
But the software isn't there, the APIs necessary don't exist in OS4.1. VT5 is not a solution for Amiga users.
Open Video Editor is, and even in it's infancy it runs circles around the original Video Toaster software. Video Toasters are for TV stiudios, if you are making Youtube videos or other videos which don't involve a live digital signal you are better off with Final Cut.
