I have a JVC Everio GZ-MS100 U Memory camcorder. The footage is great quality when I playback on the camcorder or link it up to my TV. As soon as I use the USB cable to import it to my lap top I get a choppy result.(Same if I import it with the SD card) Audio is fine. It is just the video. \nI use Nero to author the video.\nAny advice would be much appreciated. I am disppointed with the results.\nThanks.
