There are far more people in that thread that share that opinion. I haven't really heard anyone strongly express the opposite opinion- that they've used DLP link and... ANY other kind of glasses and not prefered the DLP link.
When I talked about reviews of DLP-Link problems I was not refering to this thread (which I didn't read), but to several threads on AVS and other sites (including MTBS3D). These come with images showing the difference between DLP-Link and non DLP-Link 3D, and they illustrate quite well the problems I talked about.
At any rate, I don't have a dog in this fight. I just thought some of you would like to know what the masses of HD33 owners had experienced.
I just pointed out that the opinion of that one guy in this thread can't be extended as a general case. And even if a particular model of RF glasses is worse than DLP-Link, it doesn't mean that RF is inherently doomed. If properly implemented RF should be a lot better than DLP-Link, and better than IR too which have its own share of problems. That's pretty much the reason why 3D Vision Pro does use RF and not DLP-Link nor IR. Bluetooth is also another technology that is interesting and which is already used in several models of glasses (Samsung for example).
