PVR Playback Freezing

[wireless]

We have 1 PVR and 2 Digital Boxes in our home. Whenever we are watching a recorded show on our one upstairs digital box, it constantly freezes and jumps ahead. (Live TV seems to work just fine.) We purchased the Wifi Boost in the hopes that it would help the signal, but it just seems to be a waste of money because it hasn't boosted anything. We don't have this issue on any other box in our home.
