At the very least, this would result in horizontal banding.
I was wondering if this happened at the layer change, but you said your master doesn't show these problems. Maybe try ripping the MPEG with a different program and inserting that version. If the problem continues, then there might be a flag in the MPEG that is messing with Premiere.
