Blu-Ray playback

Takaharu · May 7, 2011, 11:42 AM

The PC used for our home theatre system was acting up yesterday so I (for some reason) used my main PC instead. I transferred over the BD-ROM drive and booted up, played the disc.
However, during playback the video kept lagging out - the audio would carry on but the video would freeze for a second or two then catch up. This happened quite frequently at random intervals throughout the film; no particular interval, no particularly graphic-intensive scenes, nothing obvious. This is the first time I've witnessed something like that happen, Blu-Ray or otherwise.

This was the first time that my PC has ever played a Blu-Ray if that makes any difference and I wasn't connected to the Internet. All background applications were closed, no AV scan running or anything like that.
The Blu-Ray was Tron Legacy and playback was through PowerDVD 10 Ultra. Audio via optical, video via DVI to HDMI cable.

Has anyone got any ideas of what it might be?
I'll post the model of the BD-ROM drive when I get it.

Do look task manager if there is any app's hogging resources. That's might be the case....

btw. DXVA on or off?? And what GFX card?

Strange, is PowerDVD set to use PureVideo hardware acceleration? Looking at your specs I wouldn't think a bluray would cause any problems for your system. Maybe some kind of conflict with SLI.

If it was me I would make sure everything is updated. Bluray player firmware, PowerDVD & Nvidia drivers although I expect you have already done this. Maybe the disc needs cleaning or even the lens of the Bluray drive.

Blu-Ray drive is a Pioneer BDC-202 and is updated as far as it will go. PowerDVD is updated and graphics are also up to date.
SLI was disabled during the playback of the film - I usually have my PC in multiple display mode, rather than SLI or Surround.
No background apps were running at the time; usage of memory and CPU was insignificant.
DXVA I don't know. What is it and where is it?
PowerDVD is set to hardware acceleration.

DXVA = DirectX Video Acceleration
Well if the HW acceleration is on then DXVA is on. Could be buffer issue on the drive or RAM.

I had a similar problem until I updated the TV firmware. Though, it was more stutter than lag.
