I would like to echo sdschramm's comments about the granularity of the blocks available to select in Re-Edit Commercials. Tonight I watched Monday's episode of American Idol using the beta version of the iPad app on a Mac mini while doing other things on the Mac. Many of the commercial cuts included about 30 seconds of ads before getting to the cut, so I would go over to Re-Edit Commercials to make an edit, but in all cases, the ad portion was grouped in with the main program and I was not able to make an edit to report. There was a single edit that I was able to report when a few seconds at the beginning of the program were missed.
It's interesting that sdschramm complained about ABC World News and American Idol is also on ABC. I have not noticed this issue on other networks. I do not record much from ABC, so I will make a few other ABC recordings to see if this is specific to ABC in general. By the way, I am using two HDHR Extend tuners for my captures and my ABC station is KGO in San Francisco.
I did read the link posted above about using LosslessCut get more granularity, but I have not tried using it. It is not clear to me that edits made by LosslessCut and shared would help improve Enhanced Commercial Detection.
