Thanks for the reply.. only thing on your list that I haven't already investigated is changing the audio output method. I'll give it a try when I can dig out an old analog cable and see if it changes things.
Is the much reported problem in earlier versions of PowerDVD (and other companies players) with separate audio and visual clocks still an issue in version 13? Apart from your idea with the audio output, it's the only thing that makes sense given the pervasiveness of this issue despite changing hardware, OS, driver versions, etc. My machine is way overspec, passes the 3D Blu Ray analyser and has minimal resource usage during playback. I've spent so much more time trying to fix it than I have enjoying the movies. I'd give Reclock a go, but it doesn't seem to like either PowerDVD 13 or Win 8.1

Opened a support ticket with the below info, figured I'd post it up here in desperation as well. Thanks in advance for any help.
**********
I’m getting some pretty nasty episodes of irregular stutter when playing back 3D Blu Rays. Episodes occur every 2 – 5 minutes and last 3 – 8 seconds. Appears to stutter + drop frames. Audio remains smooth. At first, I thought it was only occurring during fast action, but after a more careful look, it seems random, it’s just more noticeable in action sequences. Occurred with every 3D Blu Ray I’ve tried.
I’ve Googled and read up heaps on the issues people have been having with Blu Ray stutter on PDVD, a lot of threads are unsolved. The few suggestions people had for fixes I’ve tried, with the exception of Reclock, as it doesn’t seem to work on Win8 / PDVD 13.
CPU usage sits barely above idle when playing back, no visible spike when stutter occurs. Computer specs are below. Plenty of free RAM and HDD not getting thrashed. Hardware decoding is working fine.
All drivers up to date (and have tried multiple old video drivers with no change). I have the exact same issue on my old media PC with low end hardware, since fully rebuilt with new hardware and fresh Windows install, same issue, so I guess I wasted a lot of money there.
Turning off all post-processing features on the TV also doesn’t help. PDVD is setting refresh rate to 23.x, which seems appropriate. Tried manually forcing to 24, but gets overrided by PDVD. Resolution is 1920x1080.
Power DVD 13 (fully updated)
CPU: Intel Core i5-2500K
GPU: NVidia GTX 650 Ti (current drivers + tried many old versions)
RAM: 8 GB
Blu Ray: Pioneer BDC-207D
HDD: Samsung 840 Evo SSD
OS: Win 8.1 (fully updated)
TV: Toshiba Regza 55” 3D LED (direct link from PC with high speed HDMI cable)
Audio: optical link to AV receiver
After seeing so many people having issues and without decent solutions, I’ve come to the conclusion that PDVD is deeply flawed for Blu Ray 3D. I’m not sure if it is the issue with asynchronous video/audio clocks that Reclock addresses or something else, but either way, PDVD seems to be a huge waste of my time/money.

Thanks guys!!! I updated to the beta and it's now working great, just like PD11 did. Wasn't so keen on rolling back the driver due to the significant BF4 performance improvements in the last couple of revisions. Might pay for Cyberlink to update that FAQ (http://www.cyberlink.com/support/product-faq-content.do?id=16772) as it doesn't really talk about performance issues when previewing, just the appearance of the bar when adding clips (which wasn't really an issue for me).

Hi guys
I recently upgraded to PD 12 (from 11) and I'm noticing that the preview seems extremely slow... it's playing back exactly a 1 second chunk then pausing to render the next second, then playing one second, etc, etc. I don't remember this behaviour from PD11. It happens on unedited files I drag into the timeline and try to preview. Interestingly, if I open up the trim box, i have flawless playback in there while chopping files up.
It also doesn't seem to matter what quality I have the preview set at. It also doesn't appear to be a hardware issue... my CPU/GPU/Disk access is barely being taxed (< 25%) and there is plenty of free RAM (23% used of 16GB). Source files doesn't seem to make a difference, same behaviour with vids from my Canon P&S, Canon DSL and GoPro and a a friend's Nikon DSLR (so some .mov, some .mp4, with a variety of frame rates). It's really starting to annoy me while trying to edit. Anyone have any ideas? I've had a bit of a Google and a look through the forum and most reported issues with slowness seem to be definite hardware issues, whereas mine isn't. Is this related to the "pre-rendering" issue reported with Nvidia drivers? It doesn't sound quite like the behaviour reported with that bug.
Thanks!
PD 12.0.2230.0
Win 8.1
Intel i7 4770K
