I ran across this video today of the 4000 having several hiccups...
It kept relooping for at least almost 7 minutes in the video.
There's a catchy production music playing for about 2 1/2 minutes at the beginning, it also reloops the first time the 4000 reloops in the video.
At 1:08 mins in, the 4000 is terribly degraded.
The Travel Cities Forecast comes up frozen after the almanac and then starts moving from the forecast for Dallas onward.
Trammell Starks kicks in at around 3:08 mins in and plays for the rest of the video.
The Extended Travel Forecast pops up randomly twice briefly.
This video is from the evening of December 2, 1996
