If you know where the dropped frames are, you can capture before and after them, and splice in the video. I did something similar when I got a dropped frame in the last five minutes of side one of ANH.
"Laserman is right about needing a turdload of storage space. The 200gig drive I fitted this week is too small! 300gig drive on order."
Try capturing in Huffy. It averages a 4:1 compression ratio. It's cheaper than a bigger hard drive, and you could fit all three films on your 200GB drive.
