    Laggy video

    ok i have an avi file and the video is fairly laggy but the audio sync is fine but when i try to convert it the audio is way off and the video runs even slower.

    What format are you trying to convert the AVI to?

            Try to use "Nandub" (a variant of virtualDubMod) to correct the audio. Go to "File" > "Open Video File". Under "Video" select "Direct Stream Copy". Under "Audio" select "Interleaving" > at the bottom there is an "Audio Skew Correction" option. Enter a value that will correct the synch issue, and then go back to "File" and "Save AVI" (F7 key).

                But otherwise, is it in synch? Also, you might have a damgaed AVI file. Download a utility called "AVIFixP". See link below:

                    Load your original AVI file into "VirtualDubMod". Go to "File" > "File Information" and post what is listed in "Video Track" and "Audio Track" sections.
