Perhaps you inserted a link in the link farm. The reasons can be different. Aslo do you have unique content

I have a theory I think you have been penalised for keyword stuffing, though in this case it might be a little unfair, have a look in your source you will see that the channel numbers are all in a span class followed by the line breaks, I'm guessing big G thinks this is your attempt at keyword stuffing. The solution, well ironically use a table (2 columns multiple rows), after all what you have here is tabular data and it is what tables were designed for.
