VCR capture - white band with nvidia -please help

I have been capturing analogue footage (VCR and camcorder) and converting to DVD. I have managed quite a few very successfully using Intervideo WinDVD recorder 5 through my Nvidia Geforce 4 MX 460 graphics card. Suddenly the capture appears to be ok but when i play back it has a very wide white band across it and is unwatchable. I found a reply on another forum that suggested that it was due to the erroneous loading of the WDM drivers and that i should reload. I have tried everything and even used drivercleaner to ensure that only the latest drivers from the nvidia site are loaded. The white band is still there, Please can someone help as i have alot of analogue footage of my young children that i want to convert!
