The data in the Guide seems to be incorrect for An Idiot Abroad: The Bucket List on Science Channel HD.
All of the episodes (which only started airing earlier this month) display "First Aired" dates in the Fall 2011 time frame. For example, the episode that will show on Saturday, 2/25, (when it normally airs) has a "First Aired" date of 10/14/2011. I have a Series Link for this show. None of the episodes have recorded this season. I believe this is because the "First Aired" date is wrong.
When I search the shows with the Directv iPhone App, I get the same data as I do on my HR20-700.
