After 2 days of testing my new NEC 2500 I discovered that all my DVD-R that were burned (with Pioneer 104) will give read errors.
Pioneer will read them with no errors.
I burned Optodisc -RW and Prodirc +R with NEC and chacked them with DVDinfo. Got read errors. Again Pioneer very few recoverable error on Prodisc.
NEC has 1.06 firmware and was built in January 2004. It may be a good burner but bad reader therefor it’s going back to newegg.com.
