First of all Hello to all! Glad to be a member of such an informative forum!
Now if noone minds onto the question.
I have an HP m7350n PC ( link to specs http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00585745&lc=en&cc=us&dlc=en&product=1818343 ) in which I have upgraded the video card to Nvidia 7600GS and put in an LG HD-DVD and Blu-Ray combo drive with a SATA connection. Here is my issue. Even on a fresh install copy of windows vista or xp (Both vista 64 and 32 bit) the play back in PowerDVD 8 Stutters, especially during high action scenes. To play it I also use SlySoft AnyDVD. The movies in particular that stutter are The Simpsons Movie, Ratattouile, AVP 2 Requiem and Beowulf (last one is on HD-DVD). The one movie that seems to play find however is Troy Director's Cut on Blu-Ray. I suspect that my computer is underpowered, and if that is the case what can I do/upgrade to speed it up. Also, is there software/codec that would play blu-ray movies more efficiently? What about CoreAVC?
I should also point out that I am watching it on a 20 inch lcd monitor with a resolution of 1680x1050. I do not yet have a high definition tv, but I was planning to hook up the pc to it when I do get it (if I can get this stuttering fixed)
Final note, I have also tried it in Nero Showtime, which was worse.
What would you recommend that I do?
Thanks in advance
