As I read the post, the volume loss was with either 2D or 3D material. The trigger seemed to be 24p output being enabled.
If Pioneer is "aware" of the issue, this means that they are still trying to categorize the disparity as a "problem" or a "feature". Unintended "features" are less expensive for manufacturers, as they don't require a fix.
I agree that people jumping into the 3D world will likely face numerous compatiliblity issues and challenges over the next year or so.
Based on this thread, it appears that Denon may have fewer issues (or unintended features) than the other brands.
Key to selection at this point may be ease of firmware update process and the history of the manufacturers in developing needed firmware fixes.
Onkyo, for example, had had a history of not posting firmware updates for their lower end receivers, requiring owners to ship them to a service center - at the owner's expense - to have a simple fix applied. The 600 series fall into this lower end category.
The firmware updates for the 608 can be done by burning a disc and using the optical in on the receiver, but Onkyo does not support this being done by the user a and doesn't publish either the firmware or the process for updating.
To me, this is an important buying decision, affecting both the overall cost of the unit over time, and the issue of having to unhook everything and incur the expense of mailing + downtime.
