Thanks for the many replies this post has generated.
My system specs:
3.0 GHz Pentium 4
nVidia 6800GT
2GB RAM
LiteOn BluRay player DH-4O1S-11
Bundled Software PowerDVD 7.3 BD Edition. (Supposedly equivalent to ultra edition except it only allows you stereo sound)
I have also tried the evaluation version of ArcSoft Total Media. (Anyone proven this product works? I got about 10 seconds of sound out of this for Simpsons Movie, haven't tried with any others yet).
I can't believe this system is not enough horse power to play a high def movie, and if it were lacking I would still expect to see some form of choppy picture displayed. (Can still play recent games like Call of Duty on it at HD resolution and acceptable frame rate).
I've tried to get HD playback for blu-ray using a Pentium 4 3.4 GHz. No chance! These CPUs in their day were famous for their grunt, but nowadays they are very tardy when it comes to exectuing SSE2 instructions and they are actually pretty useless for Blu-ray. The latest Core 2 Duo processors,. not only being dual core can run SSE instructions in a single clock cycle. Clock for clock, they are four-five times more efficient than an old P4 for HD decoding, eg my C2D at 2.66 can do Blu-ray H264/trueHD at 75 percent CPU, with no GPU acceleration. My P4 3.4 can barely play MPEG2/DD.
Without GPU acceleration, the fastest P4, even overclocked to 4GHz+ will hit 100 percent cpu on anything other than MPEG2 blu-ray playback. VC1 and H264 will flood it to death
And that's without HD audio such as trueHD to consider!
Is your system AGP? If it is then you have one last chance to make this rig play Blu-Ray - a Radeon HD2600 AGP version. This card has the Radeon UVD (unified video decoder) onboard, which will do all the decoding of BLu-ray for you. All your CPU has to do is decrypt the aacs and decode the audio.
If you have PCI-16 graphics slot, you can also choose a modern N-vidia such as an 8600. This also does nearly all the video decoding for you on Blu-ray movies. Be aware that high end graphics cards rarely provide more GPU acceleration than low-end ones, as they are targeted at gamers and not HTPC. Don't imagine, for instance, that an 8800 will be better than a 8500 for blu-ray.
It may be worth a try.
