Just a post to point out a really good intitiative on the web:
Here is a container creator that converts RSS video-feeds into containers you can import in your zapper.
It's cut-and-paste, so really easy to do.
The guy has a nice example of it online, which converts the
yahoo movietrailer-RSS's (what's the plural of RSS?) into
this container.
Give it a try! It's a bit slow, but that's because the pages are created on the fly.
