Brian ...

You'll need Premiere 1.5 with the 1.5.1 download to capture and edit HDV on the Sony.

Alternatively, you can download some freeebies (just google for them) -CapDVHS is a utility for capturing HDV, and VLC media player, which will play the resulting transport streams (Media Player won't). Then at least you can capture and watch the footage. I recently used both to capture and play some HDV footage on an old Sony VAIO - DVGATE doesn't know how to do HDV.
