SMPTE problem in Hog iPC

I'm running into a problem where the SMPTE time is not reading correctly on a Hog iPC. It's a steady time code stream from the source, but when it reaches the iPC, the console is "jumbling" the timecode. It's not steady and is making timing sometimes late.

I've checked the cables and SMPTE source all the way to the console and that is good. I've also traded console and am having the same problem.

Is there anyone experienceing this problem? Any help would be greatly appreciated. Thanks.
