Personal video recorders (PVRs) haven't exactly set the world on fire
commercially. Despite anemic sales, analysts insist that PVR technology will
prevail and change the way we watch TV. Unlike a video cassette recorder (VCR),
which relies on tape, PVRs record TV programs to a hard drive. That lets users
more easily record and play back the shows they've captured. Moreover, it allows
for time shifting-stopping a live TV show with the push of a button, then
picking up where you left off at a later time because what you missed has been
recorded...
