Does anyone know if federation training videos exist for officials in terms of rules and mechanics? If so, where can you find them?

I've been searching for some as well, but haven't found much yet. I did pick up the Dick Honig DVD re the referee position. It's available through Officiating.com. I'd say it's applicable for either fed or college. Some good stuff in there.

But rather short.

Yeah, can't argue with you there.
