Not all HD is the same. Codec and bitrate have to be considered. Your MKV
files could even be variable bitrate, so some parts will work fine, others
will need more CPU than you have. If you are working with h264 at a decent
bitrate, non-ION Atom is worthless, IMO. The only way to fix that would be
an add-on GPU, PCI or PCIe should work. All of my FEs run VDPAU, even though
one of them has a good enough CPU for most anything. It's just smoother and
this way. MPEG2 from US-OTA worked fine, but these BD rips just chew through
CPU. With ION so commonly available with good pricing, why bother with
anything else?

Note that most downloaded/streamed content is probably low bitrate and may
work where other files you have locally won't. I don't use Miro, so I can't
say for sure on that, but from reviews for various other services seem to
all say the same thing that way. Much of that is probably to deal with the
lousy internet connections most people have. Streaming a full rate BD isn't
going to happen over most US internet connections anytime soon.
