Professional Video Encoder -NOT- for Editing

[[Mike of the Desert]]

When it comes to video stuff, I usually run away from the universal rule "Google it", so.. Guys, I'm asking for an advice.

What is, in your opinion, the Best and most Professional Video Encoder (for converting any extension to any other) out there?
I actually don't mind to Buy it, if it does work well.

I don't need it for editing, but for playback issues, since I usually work with Mov files and well.. They are a Bitch for common things like Ps3 Consoles and stuff. I just don't want to use a sad free converted, quality and stuff is something I really care of.

Any idea?

Avisynth + VirtualDub. Both are free and you can basically convert anything with them.
