I don't rate the Ritek DL's I am afraid they are too inconsistent for me, check out Drives/Media forums for scans with that media. That said if you have been problems with the Verbs as well that sounds odd - did you manage to burn a new Verb DL after the firmware update to 1.29 ? I have a Pioneer DVR-111 with 1.29 and it loves the Verbs...
