I had this very problem. Choppy blu ray playback and I tried everything, but eventually I found this thread and changed my 400 watt Chill-Innovation PSU with 700 watt of the same brand and problem was solved. I even sit and write this on the same computer on dual display while blu ray is running smooth on my projector.

See the 400 watt was not enough even though the system only used 130 watt at all time. Probably because one of the PSU outlets couldn't manage the load.

The kind of choppiness I had was maybe once every 5 seconds and then the feeling that a frame was shown twice. I could even after a restart of the computer experience maybe half an hour with smooth playback but never an entirely film.

I am watching at the moment Planet Earth from BBC

The things I tried but didn't work was changing my graphics card to a Asus EN8600GT, adding more memory (from 1 to 2 GB), reinstalling system but in the end it was the PSU that solved the problem.

So thanks for the PSU tip.

Maybe I was a bit too quick above....I still have the choppy playback. Really annoying. My system is:

Asus M2R32-MVP motherboard
AMD AHTLON 64 X2 5000+ CPU
Asus EN8600GT gfxboard
Audiotrak Prodigy 7.1 HIFI soundboard
2 GB RAM Kingston Valueram
Pioneer BDC-202 BD-rom drive

It is usually only when a movie has been running for half an hour that it start and then it is not all the time but only sometimes.

If anybody has any ideas it is very much appreciated, because I have run out
The only thing I can now think of is that my blu ray drive is the culprit.

Best regards,

run this in the tray and watch your temps

It looks like the core temperature is around 22-23 degrees celsius. And the Nvidia shows 61 degress celsius for the GPU

no problem there
see if there is anything in the error logs at the time of the problem

Glad to hear that.

I got an idea. Could it be that there is a bug in PowerDVD. By searching the internet there is really a lot of people having problems with choppy blu ray playback even with fast systems.

I tried out WinDVD yesterday and it seems that playback is much smoother. I have always liked PowerDVD because their scaling simply is the best, but even so WinDVD looks like it is doing a better job.
But I shall still test a bit more by seeing a whole movie. It looks like the problem always arises when I have watched a longer period of time.

I also noticed at some point that after a restart of the system the choppiness was away and then if I played some video in Media Player and then went back to blu ray it got choppy.

if your drives are ide check they are running in dma mode and have not dropped back to pio mode

broch

My drive is SATA so it shouldn't be the problem.
I still think it is software issue...I don't have the problem with WinDVD.

I can't say exactly why. It could be a conflict with some drivers. Maybe my soundcard drivers does something who knows. The Audiotrak isn't so common.But thanks for your time.

check with power dvd for an update

broch

I already used version 2021 of PowerDVD 8, I think it is the latest

broch
