Can't Pause or Rewind Live TV

[Rick5472]

On one of my HD DVR STB's I cannot pause or rewind live TV.  I can do it on my other HD DVR STB.  Is this a sign of the box going bad or is there something else?  I can pause or rewind recorded programs but not live.

Thanks for any info.

Did you try recycling the dvr by unplugging it for 30 secs then plugging it back in?

Is the hard disk / DVR storage full? I'm not 100% certain that would matter, but it makes sense in my head.
