B&H has a lot of good videos here: http://www.youtube.com/user/BHPhotoVideoProAudio/videos . many of these are equipment specific but still good info. Some of my favorites are Syl Arena's videos here: http://www.youtube.com/watch?v=5byuHJ9uBns&feature=plcp and here: http://www.youtube.com/watch?v=Ojzbf...feature=relmfu. and you can find a lot more from Syl Arena on you tube.

Good Luck,

Bob
