Any site to watch the pokémon X and Y season in English dub?

Sometimes Youtube won't have all the videos you want to watch I know I've had that issue before. There's also a website called dailymotion where you can watch episodes of Pokemon, although I've watched the episode "Battling the King of the Mines" on that site, and I must say the quality on that site isn't the best, but you can try that site and see if you like it, if they have the episode on there.

Google is your best friend, you'll get a lot results there. I wouldn't bother with YouTube since the dubbers will have a 3rd party copyright claim and it'll be taken down
