Hi Chad, Eric, (Eric reported problems with a DVD-RV32)
No progress has been made on this. I did work with someone with similar problems using an in-dash cd/mp3 player, but we could never find out what was wrong. We tried a few different encoder options (disabling various features that were added since lame 3.70 - 3.70 didn't have any problems) However, that may have been a different problem because IIRC, it only showed up at higher bitrates. Is there anyway you can capture the output of the DVD player? Just record from line out to line in on your computer would be fine. Then send me the original mp3, and the new file in .wav format (just a second or so of data on each side of the glitch). That way I can find the exact location where the problem occurs, and trace it back to the exact frame or frames which are being decoded incorrectly, and see if there is anything strange or unusual about those frames.
