I want a really good DVD to burn some of my home videos I've converted to DVD. TDK says that their scratchproof discs (DVD-R47SPAEA) are 100 times more scratchproof than normal disc so I thought they were a good choice. Anyone know how the reliability of these discs are? Do they burn well and last long? They are pretty expensive so I hope they are good. I can buy them for about 7 dollars each.
