cardrunners has some vids, but not very many, are you looking for ring games or sngs, I find that books on limit tend to not get as dated as nl books. If you build a solid foundation, you can then work on aspects of your games and get involved in the forums for feedback from other players. I have searched the web extensively for limit material and it has proved fruitless. I have read small stakes holdem several times and I feel the material is very applicable to both live and online limit games today
good luck
