I checked out the Sigma Designs website, but couldn't find details for an
8610. There was info on 8510 and 8630 etc. and they all appear to handle MPEG
2 and 4, so it sounds like there'd be dedicated silicon (i.e. low/no CPU
requirement) for decoding.
From what they bloke behind it said, it sounds like he expects it to cope as a
Myth frontend as he specifically mentions MythTV. Also bear in mind that
these things are targetted at STB's, so they should have the grunt to do the
