To me, the idea is to wipe it clean of all the proprietary code and go full FOSS, if possible.
If all you want is a shell, I don't think you'll get one, but give it a try. pins 407 and 406 on the Xilleon 226 chip are the ones to try first. My mother-in-law has a stereo microscope that would be good for examining the underside of the main board beneath the CPU to gather clues if the pins are brought out. I wouldn't see myself getting it for a couple weeks.
Well the chance of having a "MythDHG" is less than hell freezing over.
So many things would cease to function that the effort involved would eclipse the benefit.
Cablecard would not work, so at best you would get is in the clear QAM/ATSC channels, which you can do for far less by other devices/methods easily.
Unless of course some FOSS developer has implemented a cablecard interface/API and knows how to authenticate and pair the card to the device.
That would be really cool, since if the hardware was functional, with a FOSS implementation, the premium content could be stored decrypted and in the clear on the HDD.
Additional possibilities include-adding the LAN connector and adding Tivo'esque transfer capabilities, or even better, setting up a NFS share and exposing the clear ts's stored on the device for other household devices to stream......
Maybe the XBMC developers have been working on this in the background waiting for the Rovi guys to exit the business and a XBMC-DHG build will pop up in the next week. :P
Just a pipe dream though....
