I've used a Panasonic TQ-3031F (list price k$18) to do single-frame
animation recording; it's very easy.  I'm not completely happy with the
quality, though; occasional frames have one or two tiny, brightly-colored
specks.  I have a *very* early model of the recorder, and was using the
blank disc that came with it, so I might just have experienced early disc
manufacturing problems.

For the curious, I'll include a few TQ-3031F specs:

disc geometry:  54000 frames/side normal, 36000 frames/side hi-res
resolution:     >380 lines normal, >450 lines hi-res
video S/N:      >45 dB
audio S/N:      >70 dB
recording mode: luminance: FM    color: FM R-Y, B-Y line sequential
video inputs:   composite, S-video, RGB+sync, dubbing, sync, SC
video outputs:  composite, S-video, RGB+sync, dubbing
audio I/O:      stereo (~300mV unbalanced)
control port:   RS-232C, typical industrial videodisc command set
