Ok, found it..This is what I had posted:
It could be that your software disc is corrupt and you will need to download the software from the website.
Trythis: First uninstall the previous software installed. Restart thecomputer. Switch on your cam, and plug in via USB. Wait a while and seeif it is detected at all, without the software. If it isn't, you maywant to check this article:

Ifit is detected, then the issue is with the software, and as saidbefore, you will need to download it again. Try a clean install asoutlined here:

Have you gone through both links and tried them? Also make sure that you have downloaded the latest patches for your version of Pinnacle. Make sure you do not have any other conflicting software (similar video capture software). If so, uninstall them. Then try a clean boot. I see you have XP, so here's the link for XP:

Most camcorders with USB interfaces use the USB only for still imagesand possibly low-rez video. Very few camcorders use the USB forfull-rez video and even fewer have a USB interface that would be usableby Studio. Studio recognizes and uses Digital 8 or MiniDV camcorders connected to the firewire (not USB) port. You could also try using a new FireWire cable and see if that helps..
Also, is the camera on and in the proper mode? Usually the camcorder must bein "VCR" or "VTR", but check the camcorder manual. Also, somecamcorders must be running from their AC adaptor for DV capture.
Please note that Studio will only work with type 2 avi files, mpeg1 or mpeg2 video, and not Mpeg 4 format. So ensure which format you are recording in as well..
Well, try that for now and let me know how it goes..If you found that you were able to solve the issue, I would greatly appreciate a Fixya (makes my time worthwhile :). I would also appreciate if you could "Accept" my solution here:
