Just completed my first trip with AVOD. It's a very nice system. On my return flight the system froze up and and had to be rebooted. What's interesting is that when mine stopped working the one in the seat next to me stopped as well, but the problem was contained to just our two seats. As the system was rebooting, I got to watch it's boot cycle. For the technical people out there, it is a Red Hat Linux based system (didn't notice the kernel version number). There are four hard drives attached to it (don't think these are shared drives). Upon reboot, the system does enter X-Windows for a minute (though the touch screen isn't working during that time period, bummer).

It would be nice if some of the movies were 16:9 instead of 4:3. It looks like the screens might support at least a lower HD resolution, so it would be great to have that as well.
