I remember recording a episode of Startrek:TNG as a test and about 15 minutes into the record the sound cut out temporarily for a second or two leaving the rest of the video out of sync. If I understand you correctly, your method of interpolation would try to stretch the sound to fit the video. If it were done on this video that would have messed up the sound for the whole clip not just the 2 seconds where the problem was. Mark Mark
