I like the ones put out by Bugling Bulls game calls, not sure how many they have but I own a couple. I like that it is in the Northwest and they give a little commentary after each setup as to what worked and what they did wrong. Not really an instructional video but I do feel I pick up tidbits. I actually just dug out our portable DVD player to put in the camper for to watch them during hunting season.
I also have a Quarter & De-bone video by outdoor edge that shows how to de-bone an animal in the field, I watch it from time to time to brush up but anyone that hasn't had to do that job yet should watch it for sure.
