By KAREN MARTIN Managing Editor A video replay of TechUs Sept. 4 game at Tennessee on Louisiana Cablevision Channel 38 in Monroe last Thursday night revealed a bit more than just pigskin. The game film, which is produced at Tech, was shown with about 10 minutes of an explicit pornographic video dubbed at the end. Athletic Director Jerry Stovall issued a statement about the incident, but refused to comment further. RTech has learned that some objectionable material ran following completion of its playback of the Tennessee game on Louisiana Cablevision Thursday night, and the university joins Louisiana Cablevision in a public apology for this inexcusable mistake,S St ovall said. He added that RMeasures have been taken to insure that this type of mistake will never occur again.S Cablevision replays TechUs games at 8 p.m. every Thursday on Channel 38 in Monroe. The game film for Sept. 4 ran about 90 minutes, followed by about two minutes of dead time, then approximately 10 minutes of pornography. CablevisionUs Steve Wentworth said the tape is played by automation, therefore it ran until the end. Ron Phillips, Cablevision general manager said, RWhen we received the tape, thatUs the way we received it,S Approximately 50 people called Cablevision to complain or even inquire about other viewings of the tape. Tech President Dan Reneau also expressed his concern about the video replay. It Rwas a terribly regrettable incident...something happened and we need to find out what,S he said. RThatUs not our athletic department, thatUs not our team and thatUs not Tech,S Reneau said.
