Connecting the HD DVR to your router is part of a standard installation in most cases. Was the Internet available when the Directv was installed? If the installation was recent call Directv and see if they will return and get you connected.
If you want to tackle this yourself we need to know the model number (inside the card door lower right of the DVR case) of each DVR and receiver you have and whether you can play DVR recordings on other receivers in your homw (Whole Home DVR).
