cpu usage is at 100% when watching blu ray

[madhairsm]

my problem-when i play a blu ray in cyberlink power dvd 10 it will play but the cpu usage is at 100% and occasionally dropping to 90 and back up to 100.this is causing the image and audio to become distorted.the laptop has a blu ray enabled drive and its main task is to be able to play blu ray.i have tried to enable the gpu with things like pure video but they just install and do nothing to improve the image quality.i have also tried to download purevideo hd but i cant find a software download for it on the nvidia website

i have an acer 5520g laptop with -win 7 32 bit
-nvidia geforce 9300m g (256 mb)
-AMD turion x2 mobile tecnology TL-62 2.10 ghz processors.i also have 4 gigs of ram.

i upgraded the os from vista but from what the device manager is saying all of my drivers are installed.i uninstalled the graphics driver the other night and reinstalled the most one from the nvidia website so i dont think its the driver!!!a thing that was suggested to me me was maybe the disk drive driver.but i dont think thats it either because i am able to read the files on the blu ray disk!!

please please please can someone help me???

try vlc player or bs player
free to try

if you want to try another os maybe ubuntu in live session (just burn the iso) and play the br, if still suck the problem may be elsewhere than jsut drivers

good luck

This information won't be very helpful for your laptop situation, but it could be useful if you decide to replace your laptop.

After experimentation I have found that using Cyberlink PowerDVD 10 with an ATI HD gpu in hardware acceleration mode gives the best reduction in cpu usage.

My HTPC:

AMD Athlon 64 3700+
ATI HD 4350
BD-ROM is Pioneer 202

The Pioneer came with Corel WinDVD 8. The cpu usage was 100% no matter whether hardware acceleration was selected or not. The blu-ray played as virtually a slide show with choppy audio.
Installing PowerDVD 9 (and also PowerDVD 10) and using hardware acceleration reduced the cpu usage to about 25% to 30%. Blu-ray played flawlessly. Without hardware acceleration cpu usage was at 100% with choppy video and audio.

This test was also performed on my main rig:

Intel Core 2 Duo E8400
BFG 9800GT

Corel WinDVD
No hardware acceleration: cpu usage about 40%
With hardware acceleration: cpu usage about 35%

Cyberlink PowerDVD 10
No hardware acceleration: cpu usage about 35%
With hardware acceleration: cpu usage about 25%

Playback on this machine was flawless in all tests.

So, for those who want to play blu-ray on an older processor, get an ATI HD card and Cyberlink PowerDVD. I'll go out on a limb and suggest that a laptop with ATI graphics would get similar results.

As a side note, the gpu fan in the ATI card died after only 6 months. Probably would be better to get the passively cooled version.
