Sound seems to be a recurring problem! there are so many threads with sound problems... here's mine: I split a DivX file into two, and found that the first file has both video and audio - it was perfect. BUT the 2nd file had no audio whatsoever. During the encoding session i realised that the audio data for the second file stayed put at 24KB. I did the key frames thing, direct stream copy and even tried full processing for the audio, but nothing helps. what can i do?
