I second the card reader option. I just bought a new one that does SDHC. My old reader didn't. Get off the digital to analog to digital capture. When you get the files off they are a nasty format that most video editors don't like. You might want to try converting it to a different format with something like this:

While we are on the subject of helmet cams here is my new set up using a Sony HD HDR-CX-110 camcorder. I wanted to upgrade my beach cam to HD. I did some research and found a Sony underwater enclosure for $100. Pictures of this over budget adventure are attached.
Here is some video I shot using the helmet cam on the Columbia river. Turn it up to 1080 and full screen if your system can handle it:
It is a stout setup but I don't plan have someone try an unsuccessful barrel roll with it. I was planning on using it to video other riders. It weighs about 8 pounds with the helmet. I had it on for like three hours that day. If you keep your head vertical it's not bad. If you land and jerk your head it's not fun. I ride gentle and capture the glory of others.
Here is a video from the Grayland open yesterday shot from the beach. A still pic from the video is attached for people with slower systems to be able to see the quality:
It's going to take a little learning to get used to the new cam. I got a lot figured out at the GO so when I go to Surf Slam for some beach video next month it will be beyond awesome. If the seas are reasonable it might go out on the water.
The cam is recharging and I'm watching for freighter traffic this afternoon:
