There is a great knitting show on DIY (Do-It-Yourself) channel called Knitty Gritty. I record it every day so I can watch it after the baby goes to bed at night -- thank God for Tivo! :)
DIY's website has lots of craft information on it -- including knitting patterns and how-to videos for both beginners and more advanced knitters. Just click on Crafts at the top, then in the middle of the page it lists the different shows. If you click on Knitty Gritty you can click on the different episodes to get to the video clips, instructions and patterns, etc. There are also a lot of other crafts including scrapbooking, jewelry making and woodworking, etc.
Check the show out if you're interested in knitting. I've learned a lot!! :)
