If you often embed YouTube video's in your blog or web page, you'll appreciate the new Custom Tool they have added to their embed code generator. Now, rather than just pick from the preset sizes, you can enter either a height or width and it will calculate the other value and adjust the object code for you.
Great for me, because the width of this blog column is narrower than the current smallest size of 560 x 340. Of course, you could edit the object code yourself, but this tool saves you a minute or two!
