Recording a wmv file to panasonic dvr-k12d

I made a video and am having a hell of a time getting it to copy onto a blank imation dvd-rw disk. I get 2 messages, the first is incorrect media in drive and the other makes no sense whatsoever. HELP!!!

Er… do you mean Pioneer? Can’t find that drive otherwise.

Please state what your burning application is, and the content of the second error message.
