Perhaps not quite the same issue, but it seems that some makes of DVD recorder are 'fussy' about which brand of dvd disc is used. After making some enquiries, I was sent a list of recommended brands for our model (CyberHome DVR1600). So far I've used Sony and Maxell DVD+RWs, and have not
yet had any actual failures. Occasionally the DVR will not initially recognise a disc, usually when swapping from one to another, or after inserting a fresh blank, prior to formatting. Re-inserting the disc, or switching off and then back on, fixes the problem.
Another mystery is that the handbook and spec sheet clearly state that the DVR1600 can only
record to DVD+RW or DVD+R discs, but I've made several successful recordings on a DVD
-R !
