As I exercise more features I am finding more issues. I'm surprised that testers, if they a doing a through job, would not have noticed these things. II have been a software developer for 30 years so I understand the process.
1. Like I previously reported about having to exit the library back to the home page and reenter the library because there were missing item, when i tried selecting the "Favorites" box in the filter when in a Music Video library I found 4 item when I knew I had 30 or more. I thought about it awhile then exited the library back to the home page and then reentered the library and found all the items where there. Both are an obvious case where the library content page is not being properly maintained/updated.
2. Selected the "Favorites" in the filter while in a music library where I had no favorites lock up the app and I had to unplug the TV to get it working again.
3. Went to play a music file and got a message about not having a compatible player and then started playing the song and could not get it to stop until I unplugged the TV.
Then a question: Why does Movies and TV Shows libraries have a favorites tab at the top of the library, but Music and Music Videos library do not. Consistency is a good thing and in this case easier.
