How to disable abort on drop frames?

I am trying to archive hundreds of old DV tapes. Unfortunately every time a tape loses timecode the whole preceeding capture is aborted and lost. Is there a way of disabling the "automatic abort when drop frames are found" as invariably the scenes drop frames near the end of the tapes and I am wasting hours and hours of time recapturing and stopping the tapes just before the empty or drop frame bit and then restarting manually after the timecode restarts.
