I thought it was my imagination at first. But I also see the pulsing now. Either way is fin3 with me.
I wish they would have the fast forward work like my old DirecTv/Tivo box. When you were fast forwarding and hit play, it would jump back a few seconds. This was most handy when going real fast and then seeing your show come back on.
A note on pulsing.
I've recently had some time to watch more television so i can't say if it's caused by the software update or something else. But on United 93, and Elizabeth town (two different HD movie channels) as well as a recording off the Satellite HD local WCCO channel have all exhibited pulsing of the dark areas in a image to noticeable degree. I've also noticed it in recordings of The Tudors.
This only occurs on playback, and probably happens other times but is most noticeable with a dark scene as the black will move towards purple, then jump back to black, and move back towards purple.
If I pause the playback, the pulsing doesn't happen. Thus I don't believe it's my television but something with playback in the receiver.
I'm connected to a Samsung DLP 56" television, via HDMI.
