iMovie - Imported home videos not showing there.

I've used Imtoo to convert my camcorder movies to an iPad-compatible MP4 format and then use iTunes to sync to my iPad. The videos are showing on the Ipad under Apple TV - home Videos.

However, I can't see the movies in Imovie or Video Pad as it doesn't show. What do I do to allow the home videos to be visible in these apps?
