The ad is NOT in the file of your DVR recording. The receiver seamlessly switches the playback to one of the stored local ads in the reserved space of your hard drive for however long the local avail is and then switches back to your recording once the local avail is over. Again, local on the 8s does NOT use your internet connection. Even the red button local weather app and severe weather alerts popup on channel 362 works without an internet connection on receivers as old as the D1x series. (Not to be confused with the internet based TV apps you access by pressing the right arrow on any channel) You just have to make sure your home zip code in the red button app is set to a valid physical zip code, it tends to have problems if people use a PO Box only zip code or one of those virtual zips that are building/company specific that some larger cities have.
