There has been quite a bit of controversy over the new Yahoo TV beta. In order to go back to the old version, I am presenting two options to undo it, if you like.
So I wrote a Greasemonkey script that you can use to convert tv.yahoo.com/listings back to the old format. Try downloading and installing the script and see how it works for you!
The greasemonkey script actually just pulls data from this site that I've prepared. Feel free to come to this site and get your listings. Note that the listings are in EST.
