A lot of TVE channels throw up a generic splash screen "We'll be right back" or something to that effect over the top of certain commercials--I'm sure there's a strange contractual reason why--but it causes some odd behavior in Channels DVR. Comskip usually (but not always) catches them, but attempting to fast forward immediately skips them and bites into the program. If I rewind back and hit the splash screen, it's almost like a multiple-minute timer is reset and the splash screen is displayed for an inordinate amount of time.
What causes the playback to hang so long on those splash screens? I wonder if they're some kind of a popover because they often get slightly misaligned and you can catch the last few seconds of the ad they were attempting to cover.
