Service guide?

Once here flashed an article on setting up shows for Windows Media Center. Taking used there are methods for the record, I once drew your own solution: collecting data from multiple sites (tv.mail.ru, tv.akado.ru etc.) and conversion into a universal format, which can easily hawala Tvxb.


However, almost none of the sites does not give that level of detail in the program guide, which shakes itself apart. But there is no half of the channels from my cable.


What are the detailed services guide with the maximum number of channels and information? Are there any that give data in the desired format (under program)?


Starting to wonder if anything in nature, it would be nice to implement :)


UPD. What specialized formats exist on this topic? Preferably with links.
