So this last Friday, I was able to catch all 5 hours of the "Day Shift" for Five-O. The line-up was really good, with the exception of the first one:

Let Death Do Us Part (this is a whack-a-doodle episode, in my opinion)
Double Exposure (my personal fave!)
Target -- A Cop
The Bells Toll At Noon (an excellent episode, probably the series best!)
Man In A Steel Frame (another stellar episode!)

Anyway, as I was watching, it didn't seem they edited out very much. The episodes were left pretty intact. However, when the show starts, it's the wave and the theme right off the bat. There is no teaser/preview at the beginning which started in Season 9. After reviewing Mr. Mike's page it looks like by taking those out, H&I saves 31-33 seconds which means another ad! It's enough for two ads if the spots are 15 seconds!

I'm just glad they didn't stop at Season 7 like MeTV did.
