Which is the best watermark Software?

Which is the best watermark software on the net and why, and do you have a link to it?

Also does it do batch watermarking? meaning if i set a folder with 10 videos, it can watermark all 10 of them?

Please indicate the ones you list if they can do batchs or not, im interested in trying out both.

Thank you

I recall seeing a post on how to watermark video's in just a few minutes, let me search and see if I can find the link.

EDIT: I believe this is the link.

thanks, that one uses Xilisoft Video Converter Ultimate 5.1.18.1211 for watermarking.

What other software are you guys using? which are the best ones out there? and do they do batch watermarking also?
