I hate to say it, but if you had captured everything as HDV via firewire, it would have used less space than SD ProRes and there would have been no reason to recapture. However…
Did you include all the audio again or just picture, because it might need to recapture the whole tape for the audio. There is no need to recapture audio – you already have it. Make a new sequence, copy paste your video only tracks and then media manage that. Recapture mute and there should only be the pictures you need plus handles, not whole tapes.
Then copy paste the audio from the original sequence and all should be good.
