System has had a LiteON Bluray drive running the bundled Cyberlink 8 software and all was good for playing Bluray movies.
Had the opportunity to use a 3D television and watch a 3D Bluray movie so downloaded trial version of Cyberlink PowerDVD 11 to get 3D functionality.
Strangely - and possibly related to the video stutter problem which I am coming to - at 4 different points through the movie, playback stalled (wouldn't describe it as a freeze as there was no video signal through to the TV) but recovered by itself after a period of between 15 and 30 seconds.
Frustrating - and something that I did want to investigate - but any such investigation has been superceeded by issues with video stutter in the rest of my system.
Ever since installing the version 11 PowerDVD software and watching the Bluray movie, my system now has a video stutter issue.
It is most pronounced for live and recorded TV. In a 2 second cycle (approx) the video of a tv signal will (in roughly equal proportions) run OK, run fast, then run slow in a repeated cycle. The audio is not affected. Overall the video and audio remains "in sync" - so the fast and slow video sections appear to cancel each other out.
CPU usage during tv playback hovers around 5%.
Something also appears out of whack with stored video files. Xvid and DIVX files also have a slight but noticeable video stutter. Much less pronounced than for line / recorded tv - although appears to be in a similar 2 second cycle - the video will "flick" forward slightly, almost as if it's trying to catch up.
I also happen to have a straight DVD rip stored (not compressed) and this has a similar issue to the Xvid/DIVX files above when playing back.
My first step was to uninstall the PowerDVD software, but to no avail. The problem remains. Did a system restore to take me back prior to the PowerDVD install - but still no joy.
I'm thinking perhaps that the PowerDVD install has changed video codec settings - but I have no idea on how to 'reset' them. Also - how would it affect so many codecs? (H.264, Xvid, DIVX)
So perhaps it's something else - some general video setting. But I can't see anything in the Intel video configuration that relates to this.
Hesitant to do a system rebuild if I don't understand the issue - as I would like to get back to having the ability to watch 3D movies on my system, and I really wouldn't want to be "back to square one" with a video stutter issue again afterwards!
I would be very grateful for any suggestions that forum members could make - my hair is growing even more grey...
