I am having a problem with the guide times on my tivo, I am in Adelaide SA, using Foxtel Digital Cable.

ESPN, FOX Sports are OK.

Other channels such as Comedy, LifeStyle, Fox8, are about half an hour out. The tivos current time displayed at the top of the screen is always correct for all channels, but the tivo guide data is showing the program time data half an hour late (as compared to the foxtel guide at the bottom of the screen). For Example if I try and record SouthPark it records from 8:00-8:30 (as indicated by tivo guide), but the program is actually on at 7:30-8:00.

Is this just incorrect guide data or is there a setup problem with my tivo ?

Any help would be greatly appreciated.
