I don't know the inner workings of the script either, and whether it is hardcoded for a specific resolution. Sounds like the following suggestion would not be workable, but I will throw it out there anyway, since suggestions are being solicited.

Step 1: Upscale the GOUT using your favorite upscaler.

Step 2: Run the magic avisynth script to clean it up and tweak it. (This might not work on an upscaled video if the resolution is hardcoded in the script though, or if certain parameters are resolution dependent)

Step 3: If the video was extra-upscaled in Step 1, then user your favorite down-scaler to downscale the video to the desired target resolution.

I guess my main suggestion is just to try running the cleanup script after the upres, rather than vice versa. Hope this helps.

I am actually trying this out right now, so far I have learned it runs slower, and it does "seem" to look pretty good, I will encode a sample in a bit and try it out on my HDTV soon.
