"Over the air" was shorthand and unclear.
Here the VCR is attached to a cable box that connects to analog TV. The cable TV box isn't HD. It converts the digital cable signals to analog that the VCR and TV understand.
If you want to use an analog VCR to record actual over-the-air digital TV shows, you need a digital TV to analog converter box. You can still get them for $35-$40 or so.
It won't look good, though. Standard VCRs have 240 lines of resolution. AFAIK, most over-the-air HDTV stuff is at least 720p (720 lines of resolution).
Sorry for the confusion. HTH.
[edit:] Thanks Spice. I'll keep looking around. I'll post a follow-up if/when I actually decide to do something. ;-)
Cheers,
Scott.
