There are two episode of MTV's "The Challenge" tomorrow (3/13), however there seems to be a discrepancy as to the times they are airing. Both TiVo and TitanTV have them airing at 9pm ET and 11:03pm ET (the after show). But Gracenote (zap2it) has them airing at 8pm ET and 10:03pm ET. Perhaps it is some sort of confusion related to Daylight Savings? I am not sure which ones are correct, but I always place my bet on Gracenote. EDIT: The normal time for this show is 9pm ET, so it is possible that TiVo/TitanTV are correct (MTV.com also has the 9pm/11:03pm times), but in my experience Gracenote is almost always more accurate, so you may want to cover all your bases if you can.
