Overriding to Capture in FCP 5.1

[sypher1504]

I am wondering if there is a way to override FCP's calculation of how much room there is left on the scratch disk. It thinks there is only 20 Minutes left on the scratch disk, even though when capturing it very clearly has room for more video.

I am trying to capture using H.264 compression at 100% quality. It compresses it to about 80 MB per minute of video. I have 225 gigs of free space.
