Hmmm - Didn't work. When I try to load the SER file into Registax it seems to randomly crop and add blank scan lines to the frames. The SER file appears normal when viewed in SER Player, and PIPP. I have a workaround in that I can export the SER file in AVI format from PIPP, which can then be processed by Registax, but I don't know if that is a 'lossy' conversion.

So off to find a Registax Forum!

Mind you the end result wasn't too bad.
