I just downloaded my first HD+SD TV show from itunes and love the way they implemented switching between versions. I have a lot of HD shows like LOST and Weeds and currently have two versions (HD + SD) of each which clutters the library a bit. I've been playing around with the XML library file and noticed there's a new HD true/false key. I also noticed that there's only one entry for a show that has an HD and an SD version. However, not really sure where to go from here. Anyone have any idea how to make it so that iTunes groups my HD/SD shows together?
