I recently attempted to add Serbian dub of SpongeBob into remastered HD version of Season 1 because Serbian dub was never broadcasted in HD. To my surprise, HD rip of Season 1 was 23.98 frames while Serbian TV rip I have is 25 frames. I tried just pasting Serbian audio over HD video but it did not work. It starts ok on opening but quickly goes itself out of sync. Is there any quick way to fix this or do I really have to manually watch every episode and spend time cutting and pasting bits of Serbian audio to match HD version?
