I have my 93 and a WD Mybook Live NAS (built in Twonky) on the same gigabit switch and they work very well together. I'm streaming mkv, m2ts,mov and other formats without a glitch.
I'm not saying there is a problem with the cadence.
In fact, I found them very good and very smiliar to my other players.
Then, I compared the PQ with the Pioneer, and found the pioneer better in this area.
That surprised me, enough to make a lot of other tests and comparisons.
All of them confimed this fact.
We have to ask "compared to what?" and how much of your viewing is Blu-ray vs DVD or other video sources.
BR performance is more even between players than DVD.
