It's not only the 777-300ER that is having software problems with the AVOD.
Flew SQ220 A380 flight on Nov 4 in business class. While watching a movie the screen temporarily pixulated and the sound cut out. I reported it to a flight attendant who said he would send someone to check it out.
A few minutes later a guy turns up who turns out to be from Panasonic and is travelling on the A380 sorting out AVOD bugs. He said he would go and re-boot my screen for me.
Watching my screen re-boot I was quite surprised to see it booting up LINUX. When the guy came back to check how the system was going I asked about the LINUX system and he said that they used Redhat LINUX as it was free!
The system worked quite ok after that but I couldn't help but wonder what other systems on the A380 might be LINUX based using Redhat
