Need good advice on buying Silver on Silver CD-R blanks. Any info on longevity, compatibility (both recorders and players - especially with DVD-ROM readers), etc., will be greatly appreciated. Also, did anybody see any Gold (metal layer) disks with nominal 700MB / 80min capacity recently?_X_X_X_X_X_[small]Life is what happens to you while you're out doing something else...[/small]
