Here’s a nice comprehensive step-by-step video tutorial on how to Jailbreak your AppleTV 2 in order to install the aftermarket media server/player applications onto it.
Jailbreaking and adding XBMC
Apple TV 2 + Plex = AVI + MKV video playback upto 720p
Apple just revealed its newest Mac Mini in a really nice unibody chassis.
Pretty slick, more power, much less power consumption, higher price…so I’m a bit torn about whether this is all good news or not.
It’s still a pretty decent system with good bang for the buck and size! That’s probably what Apple is counting on…the fact that you can get an entire desktop system that’s the size of an external hard drive AND use it as a viable media center PC.

I’ve found a great guide on building an Ion-based mini-ITX form factor HTPC.
This is a great, affordable alternative to a media player (such as the WDTV by Western Digital or the much more expensive Popcorn Hour) and actually preferable to dedicated Blu-Ray players which have limited functionality.
