Hi Iridium,

thanks so far!
The videos are working on the pc totally normal either with AMV-tool player or the original avi format, just on the nano player they have this "hopplings".
I tried it now with several files, but still same, on the vid encoder what you suggested i "reduced" them to 160x128 and sound settings i left as they were as i didn't know what to choose. Afterwards using this "optimized" file and converted it to amv with amv utilities.
But nothing changes. btw: the sound sequences are only hoppling/echoing when the people talking, if there are normal music sound sequences sound is normal playing on the "nano".
Any further ideas?
