This just started happening recently with the audio whenever I encode avi audio with toolame and this only seems to happen with captures. I couldn't figure out what was gong on, I was loosing the audio on my files after about 3mins of play. I checked my source AVI files and the audio ws OK. I carefully watched when the audio was being encoded by tooLame and it flashed a message at the end, something to the effect of "There is not suffiencient PCM due to a frame error, filling out with 0s. I checked the temp MPA file and it was about 44MB. When I played it it was approx 45mins long. My original video was about 23mins. While checking the file I saw that there was this huge gap from 3mins until 30mins, then the rest of the audio played normally, hence the silence during the rest of the clip. I went into VirtualDub, copied it the audio as a WAV and sent it back to TMPGEnc with the video file. Although I got the same error when I checked the resulting tooLame MPA file it was the right length and all the audio was the way it was supposed to. This only happened with AVI captures. WAV files from DVD2AVI projects and all other audio turn out fine. Although I'm glad to have found a workaround to the issue and it thankfully hasn't affected my other conversions what could be causing this? Are there any settings I should check in VirtualDub of TMPGEnc? I can live with this solution but I'd like to know if anyone has experienced a similar problem.
