**RESOLVED**HTPC Bluray playback issues

So I've been watching Bluray movies for a couple months now on my 780G MB (Phenom 9600, 4gb 1066, XP 32bit, PowerDVD 7.3) using the integrated HD3200 (128mb sideport memory) over HDMI on my 50" plasma. No problems smooth as silk playback.....till I popped in Ironman. It stutters and lags all over the place, even in scenes that have very little movement. So I take it out of full screen and it gets smoother....wtf? I would think (probably incorrectly) that a movie is a movie, all my other Bluray's still play great, just not this one. I even ripped it to an ISO and played from the HD with the same results. Can anyone shed some light on this for me?


So it turns out it doesn't pay to keep your drivers updated.....after uninstalling the newest Catalyst 8.12 drivers and reverting back to the ones supplied with the MB everything runs smooth again. @#$%$@@ing ATI drivers, I can't believe the "new" ones work worse than the old ones.
 
Try running it through AnyDVD HD if you don't have it. Ironman is a new disc, and BluRay actually has several succeeding generations of encryption/DRM. It's possible this is what you're running into. Heck, I think I'll rent it myself and check it out on my system. Off to Netflix... OK, done.
 
I should have mentioned, I used AnyDVD HD to rip the ISO image, removing DRM and also disabling BD Live, no help there. Playing with the movie further I have found the extra/deleted scenes are really bad playback, so bad I couldn't even sit through them shrinking the window size down. Could this really be a video card issue? I know the integrated HD3200 isn't top of the line but every other Bluray plays back so well.....
 
Everything is updated, AnyDVD HD, Power DVD, and video drivers. Firmware on drive is current and using latest version of cloneCD to mount the ISO image.
 
what about using a different player? if it's decrypted, try MPC-HC and see how it handles it, or use regular media player classic and use coreavc or something as the decoder (assuming the vid is AVC not VC-1)
 
it could be your computer does not have enough juice?

I know on my laptop, when ever I play movies in full screen, I need to have the ac adapter plugged in, otherwise, it stutters as well.
 
Laptops throttle the processor when on battery power to extend battery life, desktops don't, and I have a 700w psu which would provide more than enough juice for what's running....I have done a bit more research though and found someone else with a similar issue who had to change their refresh rate to 24hz for smooth playback. I am still going to try MPC-HC at current settings and if I still have problems try the refresh rate change.
 
So it turns out it doesn't pay to keep your drivers updated.....after uninstalling the newest Catalyst 8.12 drivers and reverting back to the ones supplied with the MB everything runs smooth again. @#$%$@@ing ATI drivers, I can't believe the "new" ones work worse than the old ones.

Thanks to everyone for your help.
