Well I was about to give up as the PTA02 kit was terrible and the 3D was unwatchable on my 40" 8605 PFL.
Then I took the plunge and bought 2 pairs of the Xpand X104 glasses.
Out of the box they were a vast improvement over the philips glasses.
I tuned both pairs using the method described in the 3d section over on avforums which then improved them further.

The 3D is now watchable and pretty good (not perfect) but crosstalk is cut to a minimum. I can now watch a full film without having to pause and take breaks
