Aminet is not a video distribution or TV / movie related site and therfor doesn't have PAL or NTSC formats. PAL / NTSC is a set of standrads for brodcasting pictures over the airways. In Europe the PAL system is widly used for TV however it has nothing to do with AMINET.
AMINET is an internet database where people upload their programs for distribution to others.
If you by a CD, all that has happened is that someone has copied some of these files from this database to a CD for you. It is a data CD and thefore has nothing to do with PAL or NTSC or any other video standard. Think of it like buying norton anti virus or somehting like that. That CD would have nothing to do with PAL or NTSC either, it just contains the program.
AMINET is the sam, it just contains programs for you to use on your AMIGA.
Your CD collection does not contain all the files available on AMINET either. AMINET get's new files daily, so unless someone is sending you daily updates on CDs, you won't have "everyhting" so to speak.
An example. Let's say you wanted a program to read documents for you. You would log on to AMINET and search for a document program, you could then download that program and use it on your AMIGA.
Don't get confused here but AMINET is only for AMIGA / type computers. You won't find many windows programs there.
If you want to find out more, follow the link off this site and have a look for yourself. It will probably help explain all of this for you
