I have used over 50 dvd-r this week.Mostly Panasonic x4 discs,but some Verbatim x2 aswell.No problems.I would stay away from the cheap junk thats 75p or less
Riteks are a good brand and a reasonable price I have been using them for years on my PC Writer with no problems after storage, avoid princo, bulkpaq and mirrors when looking go with the type of dye used as they often change. Have seen datasafe use ritek and princo dye. Personally not used in disks in my 5100 yet
