The dv stream shows a lot of video error concealment because the data was originally stored on a dv tape and then transferred over firewire to a computer; however the dv tape player was having difficulties reading the tape (various dv dif blocks would mismatch their parity data) so many dif blocks are concealed or broken. I’d really suggest that the best way to repair this would be to work with the original tape, clean the head of the playback deck and retransfer. In a better playback environment you’ll likely get a more accurate reading of the data from the tape.
