ritek have i been gypped

[steve p]

purchased some ritek disks from bestsonic.com

they are a lot lighter in colour than the previous ritek disks i have had in the past and my recorder pioneer 104 1.31 firmware is having problems recognising the disks
the only identifacation on the disks dvd-r 4.7gb ver 2.0
and some have unaxis nimbus dvd-r v2.0 consumer l62 1296

any body advise if these are ritek or not
thanking you in advance
