Some Guides use data provided by Rovi Corp, and others use data provided by Tribune Media.
I don't think the HD has anything to do with it, It is the First Aired Date that is used by the Guide data. If that Guide data comes from Tribune Media, (zap2it.com) they almost always use the First Aired Date. Some IPGs may also take into account whether the data has an (R) for Repeat or a New tag in the data.
For instance, TiVo only uses the First Aired Date provided by Tribune and if that date is within the last 28days, TiVo will record it as New, otherwise the Season Pass must be set to New and Repeats to catch US First run of programs that First Aired in the UK or Canada.
Many TiVo's did not record Warehouse 13 S04, E15 "Instinct" on Monday, because Tribune did not have any First Aired Date listed in the data:
