I have an Archos AV700, have tried that option and the DivX option but both give the same audio sync delay. I use the latest version on AnyDVD as well. I find that using TMPGEnc with an audio delay of -200ms sorts it but it also doubles the time and means 2 tools need to be used.
What would be fantastic would be for CloneDVD Mobile to have an audiosync option so you can choose the delay yourself.
I'm deffo gonna buy Mobile when this audio sync problem is fixed, well doen Slysoft, v nice piece of software.
