The bug is not caused by a thread problem. This dotted line can always be seen, 
depending on the actual color of the left border of a frame. If I remember 
correctly, the line is well noticeable on black frames. I once quickly looked 
into the code but couldn't explain what's wrong (especially because the dotted 
line is just one pixel wide and the conversion code works on 8 packed bytes. So 
one should think that if something's going wrong then for more then one 
pixel...)

Anyways, the code needs to be carefully analysed in order to remove this bug 
but I was too lazy/busy so far to do this...

bye,
Michael
