I flew IAH-CDG on CO's NY2000 777.
I was disapointed with the in-flight entertainment. The personal TV's has a limited selection of movies, and you couldn't start them when you wanted...they kept on running indefinitely. The quality of the image was also disapointing. One the way back, the video system in my seat didn't even work. I didn't even bother to bitch at the flight attendant to be reseated. I wonder if they would upgrade you to biz class if coach was full.
I enjoyed USair's transcon in-flight entertainment much better on the A330. The picture was crystal clear, and you had a LOT of movies to choose from. The flicks started whenever you wished. Same for the music selection, very varied. On the same lines, I enjoyed the service much better on USAir.
My 2 cents.
