AdultVideos.tv - adult videos, tube sites
 

This one is begging to be developed into a tube site, video review site, affiliate site, adult rentals, or video on demand. This was a premium .tv, and the registration fee was $500/yr. I believe the premium registration fees have since been reduced/removed.

The .tv extension fits the domains keyword perfectly.
