alternating blank screen after pause

[pBS]

i'm setting up a new E350 mb with a colossus, and everything's going fine till i see when i pause, the video blanks, then comes on, then blanks again, over and over...it's not always the same length of black screen...
the audio keeps playing without a skip during all this too..

all i see in logs are weird Hiding OSD/Using Fake OSD
only happens on livetv, recordings are fine..
i have latest ver plus patches..
using evr with any codec [ms,cyberlink,arcsoft] same results..
win7 sp1
[i only paused livetv at the end,was checking a recording before that]

[EDIT]
N/Mind, it was silly me checking "use alternate OSD with missing video"

all fixed..
