My plan was to use my hdhomerun to stream TV to the touchbook, unless I can get the MythTV fronend working on the touchbook. Since it already runs on the N810 which runs an ARM processor, I believe it is possible http://mythtvnews.com/2008/03/24/full-m ... okia-n810/
I'll let you know what I find out, assuming my touchbook ships before I get frustrated enough to switch to a different platform.
There is a dvb-t version, http://www.silicondust.com/products/hdhomerun_dvbt
The ATSC version works with MythTV http://www.mythtv.org/wiki/Silicondust_HDHomeRun
, but the DVB-T looks like it works as well but is under development.
It's a more expensive solution, but it removes having to find drivers for the touchbook.
