Anyone else notice that the start times for some programs (especially with the movies channels) are deceiving? When scrolling it can appear that a program begins at X time, but when you select that specific program you discover that it actually started at XX time. Pretty much makes the Guide useless for channel surfing.
In this case,
It has nothing to do with the guide. Guide data is provided by an outside vendor. In TWC's case, it is Tribune Media Services. TMS gets their programming times from the local stations. To get more revenue from commercials, stations may start shows a few minutes before the time in the guide. TV Land/Nick is so messed up that their show beginnings and ends are often as much as 15 minutes off the time shown in the guide!
In most cases, the off time is only 1-3 minutes. For TWC, if I have a show I really value, I just add Start Time, "Record Show With Options" to begin the show about two minutes later and than select an end time of about two minutes later. It works pretty well!
