Generally, nothing is wrong with 5.1 analog. Some issues were brought up in the past day or two relating to using the Pioneer DV-48AV with the 990, which you can see in the messages above.

If the 200Hz issue didn't exist for this player, 5.1 analog would work fine for me. Unfortunately it does exist, so I need to find a different SACD / DVD-A player.
