I'm a loyal guy so I have to stick with the shows I grew up watching like Real fishing, and In-Fisherman. Anything with Lindner is a must watch, every show he films is packed with very useful information.
Newer shows that I enjoy are the Musky Hunter, Urban Outdoor Adventures, The New Fly Fisher and Fishing Alberta. I watch Fishing Alberta regularly now that my brother moved to Edmonton, so when I go visit him this year I'll be ready with locations and techniques.
Honourable mention goes to Extreme Angler TV. A very informative show, but do they only fish for bass? Mind you I haven't watched very many episodes, but I don't recall watching one with a different target species. Is this bad luck on my part, or is it the norm?
Finally, another honourable mention goes to Good Fishing with Babe Winkleman. I find this show both informative and entertaining. Is there any new 'Good Fishing' shows being filmed, or are these all older episodes?
