Go to "http://affiliate.zap2it.com/tvlistings/ZCGrid.do" - it's not a complete restoration of the Zap2it listings that I, and many others, loved but maybe more of the broken links will be restored to functioning.
The classic TV listings webpage is functional and logged me in automatically with my original username, using the current date and time, all my old settings intact, and the clickable drop down addtional information on any show on the grid.
What isn't functional (takes you to a page with the error "The requested URL /tvlistings/ZCGrid.do was not found on this server"):
- links to jump to another day or time (but you can click on the arrows to jump the grid forward or back);
- link to jump from the drop down information on a current show to another page with additional details on that show;
- links to jump to "This show on TV" or "This episode on TV";
- link to jump to "My Faves" BUT the button on the drop down information on a current show does add work to add the show (but you cannot delete it from your Faves).
Maybe someone can mess around and find a workaround to get these links working. I don't have the time - I only found this alternate URL because I had been putting off customizing a TitanTV login to match my old Zap2it setup, and I Googled Zap2it to see if Zap2it had come to their senses and restored their old version.
