Perhaps it is that one DVR does not have the latest metadata down-load. Each Hopper or DVR box may download the metadata at different times over several hours. TiVo does this, as well. In other words, all Dish DVR's (or TiVo DVR's as another example) do NOT get the latest metadata at the same time. There would exist, possibly several hours, of difference between two different DVR's, even of the same model. That's the only instance I can think of relating to different search results. In fact, VOD metadata may be a different package or stream than EPG metadata, and who knows how often the latest VOD metadata is sent out and when the DVR accepts the download? The result can be search results that are significantly different. Otherwise, if this big difference in search results persists, it could be a malfunction of the DVR like metadata on a corrupted part of the HDD. The OP should keep making comparisons and get the troublesome DVR RMA'd after speaking with Dish tech support if it is something he does not want to live with.
