Video Stuttering. Possible Bitrate Issue?

[quasar25]

Oh dang. Where do I even find out how good my TV's decoder is? I tried googling a bit and I could only find which codecs are supported, not the speed at which they decode. I'm surprised my cheap Roku can work without stutters, as I would think it would have less powerful silicon than my LG B3, which is only a couple years old.
