Where I work now has this same sort of thing happen all the time but in reverse. Sometimes network or syndicated programming comes in 16:9 via satellite and whomever captures it doesn't pay attention to the aspect ratio. The program gets ingested into the system and played out 4:3 without being run through an ARC, thus looking all squished and ugly. By the time it starts playing it's too late. But ultimately I get the phone call or E-mail. "Did you see program XYZ?" "Why did it look so bad?"
Other than archived content, hopefully as more 16:9 programming becomes available, this issue will pretty much go away by itself.
