Xprotect Enterpirse 10.1 - Live Video Freezing

I'm using XProtect 10.1 Enterprise on a small camera installation (3 Axis P33, 1 Axis P32, 1 Axis Q30 PTZ). Ever since upgrading the hardware on a few client stations from older Core 2 Duos to new i5's (that support Intel QuickSync), I'm seeing occurrences of live video freezing on the monitoring screen.

When this happens, the video freezes until the program restarts - and it's only 1 video feed. The "frozen" image remains indefinitely with no error messages, which is quite disconcerting. A few times, the only way it's been noticed is when night time comes and one camera is still showing bright sun.

I suspect this is related to hardware acceleration with QuickSync, however one of the selling points of the new hardware was that it significantly reduced CPU usage (which it does). So, it's a little tough for me to simply turn it off.

Has anyone else encountered this? Any suggestions?

Thanks.
