I tossed together this video to show the difference that I'm talking about. This is very rough example (with rough regrade).

1. Desert Scene IC Recreation - 4K (regraded to the DVD)/DVD dissolve/4K(regraded to the DVD)

2. Desert Scene IC Recreation - 4K with 4K dissolve and hard cut to the mission (regraded to the DVD)

3. Train Station IC Recreation - 4K (regraded to the DVD)/DVD dissolve/4K(regraded to the DVD)

4. Train Station IC Recreation - 4K with hard to Tuco on the train (regraded to the DVD)
