Aja Kona Lhe and Playback with Machina

Haven't use the system in a while for Video, but for some reason, now playing back HD Materials, shows a mild flashing on and off of a few lines of green or black at the bottom of the video frame instead of steady full frame HD. HD Video Output.

If I playback SD Footage, this problem does not occur.

Any ideas what could be causing this?

Before I forget, am using a HP Z600 with 6GB of RAM, and Windows 7 64 Bit Professional. Aja Lhe, with Software version 5.03.

Grin, not quite yet. But, guess I will do just that, check and seat cables, cards and such and check the latest graphics driver. For the Aja Driver, I believe that I am stuck at 5.03 since I am using the Lhe with Adobe CS 5.0.

It is my understanding the the newer Aja Drivers require Adobe CS 5.5 or 6.0.
