Recorded a basketball game yesterday. Upon playing it back, the picture froze at the 19 minute mark. The only thing that would unfreeze the picture was to repeatedly press the FAST FORWARD button. Then it jumped to the 1:12 mark. Nothing would get the DVR to play the missing section of the basketball game, i.e. from the 19 minute mark to the 1 hour and 12 minute mark. Anybody have a similar experience? Is this 0x4cd or a bad hard drive? Thanks!
