Hi Andy, You were right on time for me to test it as soon as I woke up :) This version seems much better. The skip/jump has gone away! However I notice some video/audio dropouts after a few seconds of playing, and the "too many video packets in buffer" messages too. The good news is, the 82a264ea2784 version is also showing these dropouts - I am certain it was smooth before, so a bit puzzled as to why I am seeing these dropouts now! But anyway the latest PLL VCO change version seems same as earlier versions now. I have not compared with 32KHz audio sampling yet though. Do let me know if there is anything I can check to eliminate or isolate the driver settings as the cause for the audio/video dropouts. The machine itself and components are fast and I am able to play 1080p video from local disks smoothly. It might help if there can be another independent testing on this version.
