I was capturing 24 last night and after I was finished I cut out all the commercials. Everything looked fine in virtualdub, but after I saved the AVI and watched it, there is one point where I cut out the commercial but it leaves like 4 seconds of the commercial right befor the show starts again. Does anyone know why? Some one told me to Re-derive keyframes, but that didn't work If this sounds confusing. I'll post the video clip later today.
