I am not knowledgeable in tridef software so I can't help you there. I do have a 60638 TV and when you enable 3D the picture will get bright and washed out from the white DLP link flash. I gave up trying to watch 3D on this TV and sold my 3DA-1 adapter (it came back defective but that is another story). You don't mention what video card you have in the PC. It took me a month to get PowerDVD to work on my NVIDIA gt430 with the HD33 projector and Blu Ray burner, so there could be many different issues with your 3D playback. What source files are you attempting to play back, driver issues CPU fast enough etc.
Smart enough to know better, to old to care
