Recorded video to PC problems

[CivicSpoon]

I have A JVC mini-DV camcorder that I've used to record quite a bit of video. Over the summer I downloaded (not sure that's the right term but oh well) the all of the video to my computer and everything was fine. Then about a month or so ago, 2 of the videos won't play on my computer. So I decided I'll just delete them and re-download from my camcorder...not happening. First it said to make sure that the capturing device was hooked up properly, and it is. So I reinstalled the drivers and it finds the camcorder. But now it says something about a file being corrupted and unusable.... I tried looking for an updated driver from JVC, but they don't even have my camcorder listed anymore. I've also tried downloading the video from 2 different programs; Windows Movie Maker and Ulead VideoStudio Basic 6 SE Basic. Also if it helps any, I'm using a FireWire card with a DV (camcorder end) to FireWire (PC end)cable.

So I'm wondering if anyone has ever had this happen to them. Or if anyone can think of anything that I could do to try and get this working. I've got a couple of burnout videos of my friends and I want to give them a copy. Any help is greatly appreciated. And I'll keep looking around online as well.

What file is corrupted. and what are you using to watch the vids on your computer.

I'm not actually sure which file is corrupt, it didn't say. But it was when I was trying to download the video to my computer, so maybe it was a temp file or something.
Usually I use WMP to watch the videos, but I also tried quicktime, jetaudio, powerdvd, and realone. The videos won't even play in the video editing programs that I used to download it from the camcorder.
