If you have watched the movies enough you will know what is right, and if not check out your VHS, if you are using VDub just start your file and set your start point, then go to the end of that file, which would be LD side1 right? and set your end point, then choose in VDub how you want to save that file with what compression, I use Lagarith, then save that portion, that would be side 1, do the same for all other sides and then join them up, now you have a completed movie for further processing.

Just make sure you have a lot of HD space.
