SheevaPlug, GuruPlug, PogoPlug, it's a Plugging Mess.
None of the "Plugs" are intended for A/V use, and it's unlikely you could get
a full Myth back or front end running on them, at least not easily. They lack
the I/O for backend use, and don't have the horsepower to do software video
decoding, nor do they have specialized decoding chips in them. I'm not sure
what the "display" version of the GuruPlug has in it, but it's almost
certainly some sort of hardware decoder, a 1.2Ghz. ARM does not have the oomph
to decode HD without help.
The "Networked media Tanks" like the Popcorn Hour and the Myka, are
specifically designed to output audio and video, though their usefulness for
Myth systems may be limited to use as UPnP renderers. They utilize proprietary
hardware to decode video (Sigma chips and similar), but are otherwise just
The Broadcom CrystalHD can give hardware decoding capability to anything with
a mini PCIExpress slot, making many machines capable of running as a Myth
So far the Revo 1600 seems to me to be the closest to a turn-key HD-capable
Myth frontend that I'm aware of, but it's pricey compared to the "Plug" type
The "Plugs" seem to be beefed-up versions of the ubiquitous "Slug" (Linksys
NSLU2), that has been hacked to perform many useful tasks, but not drive HD
But keep posting anything you see that has potential for Myth systems, we'll
get there, some time.
