My V3D-P arrived from China (dx.com) the other day. I'm paring this with 3Active 3D DLP Glasses bought from Amazon.co.uk (I'm quite pleased with the glasses by the way, as they haven't lost sync yet, even when looking away from the screen).
So far, I've watched Dredd and Prometheus and I've been pleased with both. Some scenes in Prometheus were a little dark, but I adjusted the "user" brightness setting and increased both brightness and contrast a few notches above default and it was fine. I'm projecting onto onto a white/grey painted (satin finish) wall, about 60" across corners.
As mentioned above, the K330 may have a few sync issues, but it'll work eventually. I've always had sync issues with this projector to be honest, even using very short HDMI cables, so was expecting the worst. Prometheus 3D root menu and continue options were probably the most troublesome, but the picture was fine, although I did see some slight colour banding on some very bright colours (e.g. white smoke/clouds), but not enough to be worried about - this happens sometimes with 2D too.
As a general rule, when resync doesn't work for me, I have to switch inputs to something that shows one of the projector's own screens (e.g. SD or RAM etc), then back to HDMI. It's almost as though the projector crashes and happens most when switching between 24p modes. This behaviour is independent of V3D-P, so is no better or worse when it is attached.
