Yeah, it apparently supports .rmvb (I have no idea what it is).
It cost €80, which would be... US $105 according to the converter. But in my experience electronics/games are always overpriced in Europe, so the price there might be closer to US $85. Just look it up.
The site of the streamer is

So far I realy enjoy the thing. It basically doesn't do anything my PC couldn't do, but it does it better. 5.1 surround sound in my living froom, a big TV screen, a remote.
The only thing that's causing me trouble is the subtitles... It only reads internal one and not external. I'm probably doing something wrong, because the box says it does support .srt and .sub.
