My Bolt's hard drive crapped out last week, so I just replaced it. Everything went fine, but now my tuning adapter doesn't work. I'm with Spectrum (former Charter area) using a Cisco TA. Spectrum tried sending hits and refreshing it, but to no avail. I found the following on the TiVo troubleshooting site: There is a known issue with certain Tuning Adapters that is triggered by specific channel map configurations. This issue becomes apparent when you connect the Tuning Adapter to a new or replacement TiVo DVR, which does not have an existing copy of a channel map stored on its hard disk. It can also happen on a TiVo DVR where the channel map copy is deleted from its hard disk by a Clear & Delete Everything command or by a software update that erases the copy. If you have this issue, contact your cable provider, or Contact TiVo Support, who can make your cable provider aware of the issue. I tried contacting TiVo support, but they were unaware of this page or what this issue is. Does anyone know what this is, and what magic words I need to say to Spectrum to fix this? Thanks!
