I am trying to combine avis in virtualdub. I was successful at this a few months ago, but now I am trying to add new segments to the one large video. I have gotten two different errors when doing this, both of which bewilder me. "Vdub cannot append the segments because they have two data streams" "The video streams have different sampling rates (10.2205 vs. 10.2205)" That isn't a typo, it actually said two similar things are different. Please help! Thanks in advance, FunkyChld
