Correct.  The video portion is read at a completely different speed as well.
No CD-ROM players known to me can read CDV-5.  They would have to have a
separate composite or Y/C video output in any case, because the bit rate of
digitized video (14 Mbytes/sec or higher) is too fast for SCSI.

No such thing exists.  The Pioneer LD-V8000 has frame store, but can't play
5-inch media.  No consumer "combi" players have true frame store (they have
field store).

So, the only solution is to run the output of a consumer combi player into
a frame grabber.
