Did you do your Capture in PrE via a FireWire connection? Capture via FireWire is just a writing of 1's and 0's from the miniDV tape, and PrE does nothing to change the data in any way.
What Project Preset was chosen?
When you place the Clips onto the Timeline, is there a red line above the Clips at the top of the Timeline?
Where are you judging the quality, in the Program Monitor? If so, Rt-click on the Program Monitor, and choose Magnification = 100%. That will be a better display of the quality, though SD material on a high-rez computer monitor will never look as good as SD material played on a CRT TV set.
Can you please answer to what Bill has asked?
