Advertisements Our first TiVo Premier kept rebooting for no apparent reason, and would never recover after a "soft" reboot, only a hard reboot by unplugging the power. Also, "Tuner Two" never had any signal on any channels. So five weeks after getting the new TiVo, a refurbished replacement is sent out. The second TiVo didn't recognize the external WD drive (TiVo certified and worked fine on the first unit), but also had a problem in a familiar area, the tuners. We live in Phoenix, within 12 miles line-of-sight to the mountain-top transmission towers of the TV stations. An amplified indoor antenna gives us signal strength in the 80-90 range on all major digital channels -- when the antenna is plugged directly into a TV. The first new TiVo reported 50-55 on Tuner One (nothing on Tuner Two), and this most recent refurbished reject averages 15-40 and severe signal-breakup on all channels (even those that are pristine full-HD when the antenna is plugged directly into the TV). Now here's the odd kicker, the person on TiVo tech support mentioned TiVo equipment is "known" to have weak over-the-air tuners... especially because there's more "equipment" in the DVR than in a TV -- claiming the signal needs to "go through" more stuff like the hard drive, and if I have an external hard drive, that's even worse. Really, he said that... as if reading from a script. Seriously, hard drives will not effect the signal -- at least, not unless the drives are creating RF harmonics that interfere with the tuner. Anyway... Is this true? Are TiVo's know for poor OTA performance?
