[vdr] cutting frame accurate in VDR?

This subject was discussed before. See what Klaus said about frame 
accurate cutting integrated in VDR:

Maybe someone knows how to convert a GOP into all I-frames? Then 
maybe frame accurate cutting could be integrated in VDR, that would 
be the nicest solution anyway...
