I just spent several hours running 3 videos through Virtualdub 1.5.10 to get rid of some video noise.  I used the Huffyuv codec version 2.2.0.  When I try to load any of them into Vegas, they are black....no video.  If I try to play them in Windows Media Player,  WMP crashes.  I opened the files in Gspot and it show they were rendered using the Huffyuv codec and that I should be able to view them.  Can someone steer me in the right direction here?  Is my verson of Vdub bad?  Do I need another huffyuv codec version?  Is there a way to repair these files without having to re-render them?
Thanks
