P2 video glitches

Adobe and forum members. I am documenting the continued existence of video glitches when playing back P2 in a sequence built from the P2 clip which was Imported from the original folder.

This has been documented on both a Mac and a PC system. Both running PrP 6.0. I can match frame to it. But it is intermittent if I close then reopen PrP.
