I planned to do the median first, then IVTC. Which approach is better? I don't mind putting the time in if it's better to IVTC each of the five first...

I think I did the IVTC before the median on my Technidisc LD, I don't think it matters if you do it before or after the IVTC, as long as the frames line up and no other filtering have taken place before the median. g-force, might confirm if I'm right about this.

What is the correct size? Someone mentioned in an earlier post that all I need to do is double the width. Is this correct? If so, please explain further, as I'd like to know!

If you're planning to make a 16:9 DVD out of it, just add borders at the top and bottom of the frame, like this;

Spline36Resize(720,296).Crop(8,0,-8,-0,align=true).AddBorders(8,92,8,92)

Comparisons need to be done against the 2004 transfer resized to 704x480 to get it right, this was just some quick guesswork and demonstration from me. The picture is quite skewed so it will be a little tough. The reason for resizing the 2004 transfer before trying to match it, is that it doesn't take nominal analogue blanking into account: http://en.wikipedia.org/wiki/Nominal_analogue_blanking Chewtobacca, gave me this very useful tip when I was working on correcting my LD transfers.

I don't know, you might also want to do some more cropping to get rid of that curved border at the left side if it bothers you. Someone else might chime in if there's an easier and better way of doing the resizing correctly.
