I have a Geosat HDVR 3500 which I have been using for about 4 years. I love it and it still works with one problem. It won’t hold memory when you power it down. Even with a soft power down, leaving the switch in the back on, it loses its entire RAM and you have to totally start over. It also takes a long time to boot up, like 5 minutes or so. But once it’s going and you don’t turn it off it’s fine. Only issue is when my power goes out I lose it all again. So when I want to watch something I just scan in that satellite. I’m about ready to get a UPS for it but I wanted to see if there was a more proper solution, maybe a software reflash? Not that I’d know how to go about that.
