I was trying to make 2 copies of a back up for myself and I noticed that instant copy processing time is cut by 50 percent with the same good results as if I was doing only 1 copy.Was this a fluke? Or was it a great discovery I found within the program and all I did was select the number of copies from 1 to 2 hmmmmmm....:D

Not really... When you first process a movie, and InstantCopy does its little five-pass information gathering, it saves that information. This can be either usefull OR a pain-in-the-butt. Usefull, if you're making multiple copies of a project. A pain, if you tried to do it once... but something didn't work out right, and you want to change it. I don't know about other users out there, but my version will always do everything EXACTLY the same for the same movie. Let's say I run a trial, and my final project is waaay too undersized for my liking. To run it again with a higher resize setting -- even if I set it for 100% -- it's going to give me identically the same file size (with the same quality) as it did the very first time I ran it. So, it seems, it's another give-or-take feature that certainly has its uses... right along with a few headaches. Like a wife!

I ain't gonna reinstall, but I may just flush my system of IC and try again sometime I'm sure I deleted the discdata files as I remember it analyzing the DVD again, but that obviously ain't enough

I've done the same movie more than once to resize and I am getting different file sizes in the results, what am I doing differently.

@Scarpad Hard saying. Do you use InstantCopy to strip stuff out? Maybe keep something the second time through that you stripped the first time... or vice versa? Unless I'm doing episode disks, I don't use IC to strip anything from my projects, opting instead to use IFOedit for a movie-only "starting point" for IC. Also, do you delete the diskdata files before starting over? I don't, since I've never wanted to chance deleting something important by accident. On the other hand, perhaps my solution lies with doing this. Either way (getting back to louthewiz's discovery) it can shorten the processing time for multiple projects. I'm not sure if Pinnacle meant it that way or not (why else would IC save information about a project?), but it does.

I don't delete the data files, and I don't strip anything out. In most cases I do the exact same sizing again , this time I just bump up the the movies destination size
