Based on a comment I offered about the front panel display and the sync button on the remote, Outlaw is maintaining a list of items to include in some sort of software update. I took that to mean that they were leaning on the programmers to start evaluating the list and determining what options are supported by the existing hardware and software, and to then begin working up an update. Bottom line: I have no doubt that an update is in the works, but it may take a while to be ready for primetime.
I'm curious about your upsample quandary. I have used a little "trick" on both the 950 and now the 990 to deal with my desire to use very different processing modes for CD's and DVD's: I have two different inputs both set to use the same digital input (the one coming from my DVD player, which doubles as a CD transport). One input (DVD) defaults to full surround processing (including Cirrus Extra Surround on the 950 and PLIIx on the 990). The other input (CD) defaults to stereo (specifically upsample on the 990). Would a method like that offer the functionality that you are looking for.
