Amazon isn't (for a change!) the cheapest place to buy this but, if you haven't got a dedicated sound card and you want to put your videos onto your PC, then burn them onto DVD, then this will do the trick. Just a few things to be aware in order to maximise results:
Its a USB connection. That it means it has to share with anything else thats plugged into a USB port anywhere on your PC. USB isn't most efficient way to transfer and, as transferring analogue data into digital is demanding of your PC's resources its definitely best to give this product all the help it can get when you are using it. If you don't, you might well end up with sight and sound sync problems. So.....
1. unplug anything else in a USB port when you're using it
2. close down all those programmes running in the background (right click on the icons on the right of the "tray" at bottom of your screen and exit them.
I found the bundled software not very useful - except when you come to burning your movie onto a DVD. Then it's great for building menu screens and chapters. You are much better off using Microsoft's MovieMaker (free download if you haven't already got it bundled). To maximise results, use Alt+Ctrl+Delete to bring up the Processes list on your PC, scroll down to moviemaker.exe, right click and select High under "Priority" (Just do this when your "capturing" video using moviemaker - you can put priority back to "Normal" after you have finished)
