NOPE, this doesn't work anymore. Don't try it.
Earlier today I noticed that TVW is now posting their content in flash, a format that allows folks to embed and share that content. Think Youtube.
Anyway, later today I figured out how to actually embed it. Seems to me that TVW didn't want to make it very easy, but I'm going to show you how.
1. Find the content you're interested in. When you're at the content page, right click (this is for Firefox 2.0.07) and click "View Page Source." Somewhere in there should be a file ending with .flv.
2. Use this code in your blog post. Replace Flash_URL with the complete url of the flash file you found in the above step.
3. If these instructions don't work, use the very helpful instructions here.
