Thanks for the compliments! I'm no expert on Laserdisc transfers, I think Laserdisc Master, Althor1138, Anctufaalb or a number of other experts could probably shed some light on the subject. I'm just glad that the information about the high resolution frames is still hidden in the low resolution frames. As one of the members noted a while ago, it's precisely the large amount of aliasing that probably makes it work so well.
I will do some more tests with respect to the AR. Although the R2D2 frames suggest they need to be stretched vertically, some of the frames with C3PO seem to suggest it needs to be stretched horizontally when compared to Harmy's DE.
