RCA seems to think there was a groove, at least when they described the
system in one of their patents:

The people who wrote the SelectaVision FAQ seemed to think so, too:
<http://www.faqs.org/faqs/rec-video/videodisc/selectavision/>
RCA seemed to think there were grooves when they talked about the system
in press releases. For example:
<http://www.cedmagic.com/museum/press/release-1983-06-08.html>
You seem to be about the only person in the universe who thinks there
wasn't a groove.
