Removing B frames after the first I frame at the beginning of a new
sequence would be no problem in VDR. Am I understanding this right that
if the first GOP of a starting point of an edited sequence looks like

  IBBPBPBBPB

then what should be done is to remove the B frames after the I frame, but before
the first P frame, thus making the above example look like

  IPBPBBPB

Is that correct?
