1:Data stream type (PCM, DD, DTS) and number of main/sub channels like I used to have on the 950.

2: Seperate options for 7.1 avoiding D/A conversions (perhaps large/small being definable for each line like the 970 has)

3: Means of seeing current surrond mode

4: Ability to retain prefered processing mode depending on signal type and input (like PCM is upsample on DVD, as well as Sat, DD is DD+PL2 on both as well, but allow other choices)
