Used this excellent little device to transfer my video collection onto DVD-R's.Had very few problems with drivers or the bundled software, although it must be said encoding takes some serious processor power and RAM, so if you've got anything other than the latest spec PC, you might have problems with lock-up's and crashes (I used Athlon 64 3200 with 512MB of RAM running under XP home).
Had no problems with converting video's of over 2hrs long onto a DVD, although the video tape must be in good condition in order for it to encode without dropping frames and making the audio out of sync with the picutre.
All in all a good purchase - it did exactly what I bought it for.
