Just took CO39 from OSL-EWR (New Years Day) and experienced the AVOD.

They had about 20 movies, 4 short programs (scrubs, will and grace, etc) and 40 CDs -- everything from Alison Kraus to Guns and Roses Appetite for Destruction!!!!

The system had to be reset twice (very early in the flight), but otherwise, things worked quite smoothly -- although one of the flight attendants thought it was a bit problematic.

I could be wrong (the GF says I'm often wrong, but I digress), but from a techno geek perspective, I think its Linux running on Intel processors, and some type of modified Windows Media Player interface.

All in all, its pretty sweet.
