Media server alternative - Boxee/ATV/Roku?

[Odok]

hi.
i'm using a time capsule to store my movie library and i'd like to add in a media server to stream directly from the tc. a jailbroken atv 2 would be ideal but they're bloody difficult to get a hold of.

any ideas what would be the best alternative?? it would need to be able to stream directly off the time capsule. i'll be running time capsule > ethernet > media server > tv (via hdmi).

boxee box and the roku are alternatives i've heard of. neither seem ideal, are there any others that would work smoothly? be good if it's simple as possible...
