Now, if this program deletes everything in the selection up to, and including the end point frame, then you would have to set the end point of the cut at frame number 91066 (00:50:38;16) for it to be an accurate edit resulting in no black frames during that scene transition and no lost frames that are supposed to be there. The closest I-frame where you are actually allowed to set the end frame of the cut is one frame back at 91065 (00:50:38;15). This leaves one black frame between the scene transition.
The way I did the edit, as described in my initial post, used an editor that could cut on any frame, not just I-frames, which resulted in a perfect edit with no black frames in the scene transition.
Now, MeBeJedi says that the Rowman edit is off by one black frame. This is consistent with what I got from trying it with TMPGenc DVD Author. Rowman claims that his edit left behind no black frames. What am I missing here?
