Sony VRD MC3 not burning

completed a video, via Nero
Sony is set in PC mode.

Nero goes thru the progress mode and usually where I see the burning take place, Nero just closes the session and takes me to the main Nero screen.

One question -
In the Nero - I have 2 burner options:
Sony DVD RW (but my PC is CD RW /DVD player & is a Toshiba)
Image Recorder - could that be my Sony VRD MC3 DVD (standalone recorder)?

Ok, now I tried to burn the video to a folder on my harddrive- also unsucessful.
I did try a reboot , but still nothing.
So then a issue w/nero and not the DVD recorder?
