hmm, iam quite confused now ...
the byte which is checked there seems to be the one where pict_type is stored 
and indeed 0x20 is part of the pict type in RV40 is P & B frames with more 
then 1 slice will be cut or so, but i dont even understand what this check 
does exactly, it is only true 3 times in all rm files i have on my HD (not 
many though ...)
