Beavis and Butthead Do Christmas Cheat Codes for DVD Video

Mistake Case
On the back of the case it states Running Time: Approximately 40 Minutes.
However, the running time is actually 52 minutes.
The Beavis And Butthead: The Final Judgement disc runs 41 minutes, but is marked with Running Time: Approximately 50 Minutes. The information for both products seem to have been switched.
