Will- Yes. *Any* of those Pioneer-based players have the following flaws with DVD-A:

1) With the mains as large, and the sub off, they do *not* reroute the LFE signal to the mains the way they are supposed to.

2) BM for 4.0 does not work at all. 2.0 does work correctly, and 5.1 is unknown because no one has tested conclusively for it. (Or, at least *posted* to that effect.)
