The 5-minute skip activated by the page up button stopped working about 1-2 months ago for me. As Provaporous said, it is incredibly frustrating if you just want to watch the last part of an episode because you have to wait through the entire episode. The page up button appears to be disabled for any program that also has regular fast forward disabled. Although pressing fast forward shows the "prohibited" icon (a circle with a line through it), pressing page up shows the usual "curved arrow" icon, but no 5-minute skip occurs. Perhaps the issue is an unintended programming bug? Example shows that no longer support 5-minute skipping for me: Fringe, Once Upon a Time, 30 Rock Example shows that do support 5-minute skipping (and regular fast forward) for me: Eureka, Psych, The Killing My DVR is a Motorola DCX 3400, and I'm in the Madison Heights/Hazel Park, MI, region.
