IM Jerry who runs Chess Network is my favorite. Check him out if you haven't here: http://www.youtube.com/user/ChessNetwork
I really like Daniel King's game reviews. You can find them here: http://www.youtube.com/user/PowerPlayChess
I like Mato Jelic's videos - short and regularly released with his own style.
I strongly recommend Mato: http://www.youtube.com/channel/UCMxK1FKAbmj2N-faTWLwNig
I've developed a better 'feel' for the game by watching Andrew Martins lectures @ http://www.youtube.com/user/YMChessMaster/videos
Greg Shahade's videos are great. I particularly enjoy his solitaire chess games, where he attempts to guess the moves of existing games by great players of the past and present.
My personal favorite is IM Greg Shahade (aka curtains), who has hundreds of these videos online [1]. There are also a bunch on youtube from other sources, but in my opinion curtains is the most entertaining (he is also quite good, the 49th ranked player in the US).
