I think some reviewers have unrealistic expectations for a tv show that was shot on videotape in 1977. And thank Ma Otter there’s a full frame version this time! The 16:9 DVD from last year(?) was pretty awful to look at.
The RCA videodisc can be had for cheap, but I don’t have a CED player and don’t know anyone who does. And it’s a crapshoot if a used CED disc won’t be heavily worn and skip worse than a vinyl record.
