This is quite similar to the question you asked on the Doug thread but once again, no. As far as I know, there are no episodes of Hey Arnold available on DVD. And there was no second Hey Arnold movie.
I think the only series that Nickelodeon made a movie out of more than once would be Rugrats (Rugrats the Movie, Rugrats in Paris, and Rugrats Go Wild!). Any series that they have made in to film is more likely to be made only once.
We can only remain hopeful. They have released Clarissa Explains it All and The Adventures of Pete and Pete on DVD. Although they weren't cartoons, they were affiliated with Nickelodeon's Golden Era.
As far as Hey Arnold goes, they don't really run anymore reruns. I'm not sure of their other network though.
