He is talking about this cartoon, which I believe was produced in France for American broadcast in 2008:

The show was infinitely better than the 90's show, which was probably the worst of the 90's Marvel cartoons. This particular show only ran one season and is already on DVD, though I believe it was canceled. It still gets rerun occasionally.
