None of these are permanent, you can always go back to your original set up -
which you don't seem happy with! 
Even more so, the Pioneer gives you 6 memory locations, so you can easily A/B(C/D/E/F) the various settings.
Will have to open the manual for this, I don't know hot it works!
since you're having the same AVR, can you suggest your own personal taste regarding your listening configuration?
I use a xbox 360 for gaming and HD-DVD
I use a PS3 for all DVD and bluray
I normally listen to :
- music in extended stereo (5.1 stereo)
- movies, I use Auto Surround (for dvd,hd-dvd and bluray)
