Last night it was even flakier... still exceptionally long samples and ridiculously long jumpbacks... but it was varying, even within the same break... One very long sample followed by three shorter ones followed by several long ones.
Again, there were several times that no matter how much I jogged back and forth it always ended up at the exact same (wrong) entry point into the show. Still had many times that hitting play even two or three samples into the program would jump back TWO commercials.
I also noted strange behavior near the end of shows... when FF'ing through the last spot of a show, it would act as normal as it ever does, but if you watched the on-screen progress bar the cursor would jump back to the beginning of the show briefly then return to the correct position.
They definitely broke FF/REW (in the Samsungs, at least) with this latest update. Makes you wonder if they even test this stuff.
