About "Last Night"

This is perhaps the most time-sensitive posting I've done.

At this very minute the CBC (Canadian Broadcasting Corporation) is running Don McKellar's 1998 apocalyptic film Last Night. The image quality is terrible. The best way I can describe it is that it looks like "up-resed" Pixelvision.

I worked for years in film and video "imaging". What happened to the interpositive? Or the cut negative? Did they meet their untimely end?
