Toshiba VCR-DVD error code D8 (Toshiba D-VR610 - DVD recorder/ VCR combo)



[qanda]This thread is about the Toshiba D-VR610 - DVD recorder/ VCR combo. Click here to see full specs[/qanda]When I try to dub from VCR to DVD on my Toshiba DVR610 combo unit, it gives me a D8 error code and refuses to dub. I cannot find any any information about Toshiba error codes anywhere. The unit is less than a year old and has been used very little for dubbing. My record medium is an Ativa DVD+R disc Can somebody tell me, please, what the D8 error code means and what to do about it? Thanks.
