Roku doesn't read MKV, but does MPEG4.
I agree about the cable connection. But I suspect it's may be more a bottleneck on your PC with streaming. I have the same issue as well, but I'm on a late 2009 Mac Mini (2.66ghz D2C, 4gb RAM, 9400M NVidia). But I can do a direct file playback just fine on my HTPC, which is the second mini with same specs.
