Please be more specific.
What Mac and what Mac OS X version are you using?
What camera do you use?
What do you mean by COPY DVD?
So now is time for some assumptions, as there is not much information to go on.
You have a camera that records its video onto a DVD.
2GB for 50 minutes of video is quite low, it seems to be highly compressed. It's not downloaded .avi files you're dealing with here.
You put that DVD into your SuperDrive (the name of the optical drive in any current Mac) and use Finder to copy the DVD.
Here is where it gets confusing.
Do you drag the files from the DVD to your Mac's HDD in some folder you prepared or one that already exists, or do you want to copy the DVD, which is something else entirely. COPYING A DVD means the data from it will be temporarily copied to your HDD, then another DVD is needed to burn the data back on to.
So can you please describe your working process in more detail, so you might get help?
The following is taken from the thread titled "
