So yesterday I got an EDGE to replace my 5 year old Bolt. Mainly to get more tuners as we were always running out on the Bolt. Setup started really well, ran thru the downloads and had a picture up in about 30 minutes. Then after about an hour the unit crashed with a Serious Error screen saying it needed 3 hours to repair. Not a good start. I called TIVO and arranged for a replacement, but let the EDGE keep running. About 30 minutes later it came back on. It has been working perfectly since then. Might not need replacement. Some things I noticed: HDR mode is useless. I don't want cable TV remapped to a sudo HDR color space. Its overblown and artificial. Off it went. The GUI is faster thanks to the newer CPU. To me, using an LG C8 OLED the picture is sharper than the Bolt. The Bolt always looked very soft and full of MPEG noise thanks to Spectrum Cable low bit rates. The tuners on the EDGE seem to do a much better job of working with the signal that Spectrum supplies. Much less noise. Also, may not mean anything but the signal level and the SNR are higher with the Edge. 100/44 vs. 94/32. Colors are much more lifelike than from the Bolt. In fact the picture is so much better I wonder if I had a defective Bolt. One of the biggest fixes for me was I no longer am getting the tuner time out that the Bolt had. Using the Bolt if I did not change channels at least every 4 hours Spectrum would turn that channel off thanks to SDV. The Edge is keeping channels live as long as I want. Must be sending a ping of some sort to do a keep alive. Was hoping that the EDGE would start to use the MPEG4 streams that Spectrum is sending alongside the MPEG2 streams, but the mapping still points the tuners to MPEG2. I can force MPEG4 if I disconnect the Cisco Tuning adapter, but then I lose many of the SDV channels. ODT temp is 51. I had to mod my Bolt to get to that temperature. So other than the weird crash, I am happy with the EDGE. A real improvement over my Bolt.
