The good news is that those recordings will continue to play just fine on the 625, even without a satellite signal. I went through the same thing the last time Dish did this kind of forced equipment upgrade. (Making the 501 obsolete.) I kept my 501 hooked up to an SDTV, and continued to watch my recordings until I had finished watching everything on it.I'm more than willing to dump my DVR 625 box for a new Wally but my wife has tons of stuff recorded on the integrated HD which she is reticent to lose.
Despite what I said above, transferring the recordings is still a good idea though, just to prepare for when the 625 hardware itself eventually fails. It is just that you may have more time to do those transfers than you may have thought, as long as the 625 will continue to play them without an SD satellite signal.I doubt it. It has taken her 9 years to accumulate her "archive". My DVR recordings can easily be replaced but her stuff is mostly hard to find documentaries -- I can't even find them on DVDs. She will be upset when she has to discard her DVR stuff -- I won't. I've suggested we buy a recorder to transfer her stuff to DVDs (or MP4 files) but my understanding is that it takes forever because it is just recording the output stream from the DVR 625.
My sister is the same way. She'll DVR record stuff that she already has on DVD or Blu-Ray, just for the convenience.The stuff I have recorded means little to me -- it's more convenience -- it's easier to view a recorded movie than to go get the Blu-Ray or DVD and load it in the player. I know, that's the epitome of first-world laziness.
