i've read some posts with people unhappy with the new version. I can say that was also waiting for more improvements, but I still think those enhancements will come with time.
What puzzles me more than what I wanted to be implemented are things that were there working and now aren't.
At the moment most of my tv series episodes don't have a thumbnail. Instead they have an icon that reveals it is a video file. The only one with thumbnails as in the past is season 4 of Battlestar Galactica.
I have just upgraded to new version and this happened. All my files are in an external USB HD.
