We now have Naruto and Tsubasa Chronicle shows on rssBT. You can subscribe to these new shows in the Shows List page.
Why weren't these shows in rssBT from the beginning? Well these shows are released by a different group called Dattebayo (or DB). Since this site was only designed for eztv releases, there had to be some minor backend changes to the site to incorporate a different group's releases.
The naruto and tsubasa feeds are updated every wednesday night and throughout thrusday.
Enjoy!
