Copying a dvd.

If you get a copied dvd put it onto your pc hardrive then burn it from the harddrive onto a dvd and then do the same with the new dvd and so on for about 100 times will the dvd at the end be the same quality as at the very start?

Thanks.

Why would you want to? Just reburn from the copy on your HD.

 

As long as you do a copy of the DVD and not a conversion you will have the same quality as you started with.
The loss of quality in copied DVD:s usually happens in the first stage when you copy a 9.4 GB DVD to a 4.3 GB. The only way to achieve this is by scrapping parts (menus, extras or soundtracks) or by compressing the film itself. In the compression process you lose quality.
Otherwise a digital copy of a digital source is as good as the original.
Added:
When doing copy of copies all errors are added copy by copy. So if you have errors in reading or writing they will multiply. That should normally not be a problem..

 

In theory you're copying a digital file, so it should be exactly the same as the origional.
