Bolt Blurry Picture

Advertisements

Hooked up Bolt last week. TWC-Spectrum. M Cable Card and Tuning Adapter. Picture is unacceptably blurry, especially when compared to crystal clear picture from Spectrum Box.

Don't think TiVo support knows what they are talking about. Claimed S/N was too high. Hmm I'm an engineer and have never heard of a high S/N ratio causing problems-that is usually a good thing. Anyway, at their recommendation, I placed a 6 Db attenuator in the cable line going to the TiVo. Brough the S/N to within TiVo "specs", dropped signal to 72% from 93%. No improvement in picture.

I'm thinking it's the TiVo. Any suggestions or comments?

 

Problem solved!! Beautiful picture now with TiVo bolt.

Turns out that TWC-Spectrum is just starting to roll out tuning adapters for switched digital channels in my area-Bowling Green, KY. Service technicians will not start training on the tuning adapters for about 2 weeks. They won't be sending any switched digital channel information for about 2 weeks. Without these signals the tuning adapter will not function properly.
I knew the tuning adapter wasn't functioning and that I was missing 20% of my channels. What I didn't know was that without the tuning adapter, when the TiVo was set on a "low" number channel, for example local affiliate NBS channel 7, which is sent in both Standard Def and High Def, the TiVo will see only the SDef. Hence the blurry picture, which I now know is what a SDef signal looks like when viewed on a High Def television. For now the problem is solved by tuning to these stations in the 900 channel range, which are High Def only.

Kudos to the Spectrum cable card call-in line. The people answering the Cable Card call-in, (866) 532-2598‬, are extremely knowledgeable and well trained and really interested in solving whatever problem you are experiencing.

Tivo call-in support is a joke. Untrained people reading from a script. They are still repeating the company line that the S/N is too high, if it is over 35. This is just absurd. What you want is a high signal to noise (S/N) ratio.

Right now I am very happy with the Bolt and have just ordered a second TiVo mini.
