Had Hopper and 2 Joeys installed Sat, Joeys wouldn't link, although recognized by the Hopper. Tech support couldn't restore them to factory default, and no recessed switch (or button combo) as with most routers to do so. The installer thought that all three units should be replaced, returned Sun and install went smoothly, and order of setup and activation (Follow install wizard fully on Hopper and no Joeys connected until live TV shows on Hopper) appear to be critical. My EHD was recognized, but showed no content, with size of drive listed as being less than drive size less actual content. Reset the Hopper and recognized, displaying all content and correct drive size. Have transferred recordings from EHD to Hopper, which play correctly, and played recordings from EHD without error. Haven't tried saving to EHD yet, but seems fully functional, different than the 922. BB and On-Demand failed to display anything after initial acceptance screen for a while, then content displayed, and successfully streamed two HD shows. No software bugs thus far, but haven't moved any PTAT to user HD space yet, as just enabled. PTAT should have an option for pre-post padding adjustment, same as scheduled recordings.
