Hey everyone, I just took delivery of my first project yesterday - a Hitachi PJ-TX100. I'm pleased as punch, but seem to have run into a problem with DVD playback via my PC. I have my ATi 9700 Pro connected to the PJ using a DVI-D to DVI-D cable. When I was using the resolution I was using before (1024x768), DVD playback using PowerDVD seemed to be fine - a clean sharp image. Of course, I wanted to try to making it even better by setting my resolution to 1280x720, the PJ's native resolution. I downloaded powerstrip to do this, since my graphics card didn't seem to be seeing that the resolution was available on the PJ. I set the resolution, and immediately noticed much greater clarity in windows with text etc. But seemingly since I installed powerstrip and tweaked the settings, DVD-playback has been blocky - there are "jaggies" on straight edges and things look quite pixellated. I tried changing the resolution back to 1024x768, but that the problem persisted. I then uninstalled powerstrip and updating my graphics card drivers to 4.10. My graphics card then did notice the PJ's own available resolutions, and I was able to switch to 1280x720 using its own control panel rather than any extra software. But dvd playback is still blocky...outside of that, in windows, things are perfectly sharp. So, I'm not sure if I tweaked the wrong setting in powerstrip and it is persisting even after removing powerstrip from my system, or what, but I'm at a little bit of a loss as to what to do next. Any suggestions? Many thanks.. edit - I just checked if the same problem showed up while playing back on my monitor, and it does. Here's a pic from crouching tiger to illustrate the problem (it's a screen grab from my PC). Note the pixellation around the moon etc.: update: I've uninstalled my powerdvd 4.x and installed a trial version of powerdvd 5; the image seems to have improved. Where I could see jaggies on swords and the like before, I can't see them now. Here's a pic from the same scene with this new version: Does seem smoother. On another movie (Tomb raider) I didn't see that big a difference, though. I think I'll try reinstalling my old version of powerdvd and seeing what happens. Is it the case that some dvd playback software really is that bad?
