I've set-up the TiVo OTA (also got a couple of minis) to finally upgrade the terrible picture quality of my amazon recast. While happy with the picture quality of the TiVo, I'm struggling with v52 and v53 errors. I keep getting the message "problem with the signal on this channel trying again. v53" at several channels randomly when I change channels. The TiVo channel strength is pretty good 67-72 (Amazon recast, which is feeding through the same OTA coaxial cable, has no problem around reception at all). I have gone through various threads here as well as suggestions on other forums ... and did the reboot drill a few time to fix this ... but it keeps happening again - very annoying. Did complete system reset as well - seems like after a few channel changes, the tuners just get locked to certain channels, and show error v53 for others. Anyone else has similar issues or suggestions? Thanks.
