Maybe thats the reason

6. The SNR reading must be between the following values to give good-quality video on all HD DVR models.

Modulation type:

QAM 64

QAM 256

Minimum SNR

23 dB

29 dB

Maximum SNR

30 dB

35 dB

You are outside the range

Lol my signal is too good? Don't think so. Shall I loosen an f connector?

Only telling you what TiVo themselves say are the ranges for snr. Dont shoot the messenger

p.s. Where are you getting your snr figures from, in the TiVo menu?

jb66 · 02-05-2011, 22:58

From the PDA when I installed it

pythagoras · 02-05-2011, 23:19

Ummmmm mines 37Db and my sd is about the same or better and my hd is definately better than my sa V+.

No, from the diagnostic page of my modem, as the signal for my TiVo, V+ and modem come from the same cable to the green box I'm assuming that the power levels and snr will be the same as it is one cable split into 3 at the house.

Never tried investigating the broadband?? modem.
How do you do that?
Getting too clever for me.

Me neither.

I think it will depend on which model of cable modem you have whether that link will work.

192.168.100.1 will work, if you have a hub username is admin password is changeme. If you have an ambit password and username is root

I guess I'll never know my SNR then

One factor that seems to be missed in all this is the setting for display type which is relevant for SD but not HD as all HD broadcasts seem to be 16:9.
There is a choice of 'Full' 'Panel' or 'Zoom' and only 'Panel' will give a correctly proporioned, sharp unstretched picture.

The local head engineer who fitted my Tivo was insistant that Virgin only broadcast in 720p and that any other output needs converting by the Tivo box( make of that what you wish)
