Just now i was able to synchronize the Audio Video Sync problem of a movie of 695mb using Virualdub...
i had chosen in Video as Direct Stream Copy and in Audio i did the necessary interleaving and chose Source and Full Processing mode and the Movie size has now became more than 1GB..Then I changed the original 48,000Hz audio to 11,025hz and still the size is around 850Mb..

what to do so that the file size would again fit to a single CD...Please Help me
