oh and by the way I plan on getting the items above working with a gumstixhttp://gumstix.com
I think a gumstix is a little slow and small for a true multimedia application but i'll try it out
for my needs of a house monitoring and control
Also gumstix isn't x86 so it would be difficult working with anything that doesn't have source code.
I also am curious on the tuner for the Linux MCE?
I just found a usb powered hd tv tuner that works in linux and had to buy.
Its a Pinnacle HDTV tuner and works good. It uses the em28xx driver :-)
