Green flecks through my HAV files

[natjen]

Hello I am noticing quite a lot lately I am getting green flecks through my hav files when I try to transcode them with DVR Studio. What could this be? When I play them on my DVR they are perfect. When the green flecks appear the video is unusable and I can not transcode it which is becoming annoying because it is almost every file now. It only takes one small green flicker and the whole file is wasted unless I cut it out but sometimes it can be right through the file. Does anyone have any suggestions on how to fix this?

Thanks.
