well first off when u are transferring videos, (with probably a firewire or usb port whatever u have) copy it as .avi files, if not mpg if windows movie maker is compatible with that, mpg should work just fine i wonder why u can't edit videos on wmm.

If you have nero, try using that for video capture, you can capture videos in a lot of different formats, and even edit, and nero can be downloaded free.

and use avi at first, dont use the converter! whack idea to let degeneration happen!~

let me know if u need more help.
