OK I misunderstood. There is no progress bar when using the skip ahead/back buttons. There is for Fast Forward and Rewind. Possibly put in a suggestion in the Ideas section of the forum to add this feature.
You can hit the OK button while a show is playing to bring up the progress bar.
That's the way it's supposed to work. The skip ahead and replay back buttons have a fixed time increment so there's no need to display the time. Those buttons aren't meant to replace rewind or fast forward.
Actually, I like the way it works now. I use the replay button for sports and the progress bar would likely block out what I want to see (especially hockey). I use the skip ahead for commercials on recorded shows so no need to know the time, I just stop skipping when the commercials end.
