Problem with duplicates

I have Sesame Street scheduled for my kids. I went to clean out episodes and I noticed a number of duplicates. For examples the title "Veggies Revolt’ was recorded twice. Once on Wed May 6, 9am and again on Thur May 7, 2:30pm. Now what’s interesting is that on Wed May 6 the show ran for 1 hour (9am-10) but on Thur May 7 the show ran for only 1/2 hour (2:30-3pm). So I guess that effects duplicate detection?
