Hi,
I'm trying to join together multiple mts files (AVCHD) with TsMuxer. It generates a ts (or m2ts) file with the correct length but the audio is getting more out of sync as the movie is playing. At the end of a 1 hour movie, the audio is even lagging a couple of seconds behind. I tried playing the file with Mediaplayer Classic and Windows Media Player (using the coreAVC codec) on different computers.

Does anyone have an idea what the cause of the problem might be? Is it a problem with tsmuxer, or maybe coreaAVC?
Thanks
