Is LimeWire a good application to use to get video content for my mobile PPC and portable video player?

I have a Zune and a mobile windows PPC. I would like to get video content. Is Limewire a good place to get video content (not porn but perhaps TV or movie clips)? What application can I use to convert the videos to mobile size?
