Hello steve001. Regarding the videos, if you have a particular topic that you're interested in, then the quickest way to find it would be to use our new search facility, located at the top of every page. When the results are returned, click 'Articles', which will narrow the search down to projects, features and blogs. If we have a video on a particular subject then it will show in that list.
We're currently in the process of 'tagging' all of our existing site content, which will make the content even easier to find. For example, all tomato-related content will have the tag 'growing tomatoes', and clicking that link will return a list of all projects, videos, problem-solving pages, features and blogs on that topic. The tags should be live on the site early next year.
In the meantime, if you're still having problems finding any particular content, just let us know. (And if we don't have what you're looking for, we can add it to the wishlist.)
