I just received IMG 1.9 this Wednesday and I love it.
Only issue I have is that when I press the up arrow during playback of a recorded program I get the chaptering screen but no thumbnail pictures are available.
I tried resetting the STB and disabling/enabling the feature and still no thumbnail pictures on any of my recorded programs.
STB is a QIP-7200 P2
I'm seeing the same thing. I received the upgrade several weeks ago as part of the slow roll for DAC 1/VHO3. Are you in Southern California or Texas? I'm trying to narrow this down to if it's a problem for DAC 1 as I haven't heard of this problem for other deployed markets.
