Upgraded to 2.2, no problems so far. Except I haven't tried my problematic files in the previous FW.
Tried the Internet TV, a bit slow, maybe because of my internet connection hehe!!!
I dont think this was mentioned on the update details, but you can now go back right away directly to the currently playing music file when you go to other menus by pressing home(or is this already fixed on the previous FW?
) Plus, you can now use the next button to automatically jump to the next track while playing a music file. The left and right button is now used for moving page up and down.
