Asus Transformer anime playback

So I just recently bought a 32gb transformer bundle. I was planning to use it mainly for web and watching anime. Web part is flawless, only problem is the anime playback. I have problems with playing 720p mkv. I tried moboplayer and MX player, both of them lags when i try to watch anime.
Is there any apps that can play anime flawlessly on the transformer?
Or should I just return it and wait for the transformer 2?

I already have a galaxy s captivate, and that plays anime well. I just want a larger screen to watch it on

i've tried both and none of them seems to work... hell, even 480p mp4 doesnt work.... i think i need to return this...
