I recently wrote about the Hippy Gourmet television program. Here's another cooking show for your consideration: Christina Cooks. This program is strictly vegetarian. Unlike the Hippy Gourmet, no fish, and, in fact, it's pretty much entirely vegan. At least I don't recall seeing her using any egg or milk products. It's on various PBS stations. So check your local listings, as the cliche goes.
I don't think there's any really recent episodes, and you'll find it's not as polished as most cooking shows you see on TV. I'm certain the show is shot in a real kitchen and not on a set. In one episode Christina bangs into her pots and pans a couple of times at the beginning of episode. And in another episode, she cooks up pasta, but never does anything with it.
Nonetheless, there's a lot of good information and recipes. In addition to demonstrating vegetarian cooking, she offers hints and tips on a healthy vegetarian lifestyle.
If you're interested in vegetarian cooking, this program is well worth checking out if it's available in your area.
