I totally agree to that - I have tried several alternative video converters with many different settings now, without any success.
The original SMC software is total crap. The support hotline suggested to use “Any Video Converter Free” as an alternative, but this does not work either. The e200 V2 is definitely the last MP3 player from SanDisk I bought.
You have a v2. So do I. I used to think like you, not anymore. All my converted videos have been perfectly in sync for the last few months. Have you looked at this thread: http://forums.sandisk.com/sansa/board/message?board.id=smc&thread.id=1447
