for the future: read the sticky, create a debug output
About your issue:
1. it's normal that SCUNet is faster on follow-up files if the resolution of the input that SCUNet is fed doesn't change, since it'll create an .engine file in the first run which it can reuse.
(engine files usually only depend on the input resolution and the SCUNet settings, so if you feed SCUNet multiple files with the same resolution an SCUNet settings, the engine file only has to be created once)
2. about the resizing. Your Input has a 8:9 Input PAR (I assume this is correct) and you tell Hybrid to adjust the size so that the height stays the same and the output has a PAR or 1:1. For this, the width needs to be adjusted to 720*8/9 = 640. Alternatively you could tell Hybrid to adjust the height instead and keep for example a width of 720, then Hybrid would resize the height to 480*9/8= 540.
This has nothing to do with SCUNet. 
3. If your reset somehow damaged existing .engine files, you could delete them. You can find these wherever your 'Default Engine Path'- or, if it's not set your, 'Default Temp Path'-folder is located. (see Config->Paths). SCUNet will recreate them if they do not exist.
