Reliable DVD copy protection using a...marker? at DVinfo.net

Ronald Lee · July 21st, 2005, 07:38 PM

Someone told me over the weekend that if I make a DVD and don't want it copies, that I can take a permanent felt marker and draw a line over the data area. The data should still read as normal by a DVD drive/set top player, but will encoutner an error when an attemp to copy it is made.

Has anyone heard or tried this? Does it work? Will it truely not screw up the data reading?

thanx

I would think it would make the disc unreadable on anything.
But I don't think it really matters as you can remove most 'permanent' markers off the data area by rubbing it a few times hard with your finger.

BTW if it reads fine in a DVD drive it'll copy fine in a DVD drive.

Oh, I forgot - I have read about people *defeating* certain copy protected audio CDs by using a permanent marker.

I would guess that if you include extra data on the outer tracks and scratch just those with a tangential line, you would thwart many copy programs that would try to copy the entire disk.

there was a line of cds released a while ago where a corrupted file was inserted at the beginning (inside) of the cd track. someone drew over it with a marker and it was defeated, so they don't use that method anymo
