Having an old, steam-driven PC, I copy my DV tapes to DVD on my Tape/DVD recorder and then rip them to the PC (no video capture card, PC far too slow for the Dongle - too many frames dropped).
BTY, I just downloaded the program suggested by Ozzietropics and converted Dolbyman's Splash Mountain TDL (9 minute avi) to mp3 in 2 minutes and it's great quality.
Thanks Oz!
If you can plug the camera to play through the PC, Freecorder will record the sound for you (saves copying the tape to the PC first).
