It means that if there was some 1080p/25fps content available, the TiVo would output it in 1080p. (However, VM don't have any content like that). Lower resolutions can't be upscaled to 1080p by the TiVo.

Most just say 720i, 1080i etc.

It's a Samsung Series 6 40" LCD.

Thanks Spiderplant! If this option was selected as well as 1080i, I presume it would be ignored and everything would be sent out from TiVo as 1080i?

My series 7 Samsung also displays the actual resolution and 50hz or 60hz as well.

yes there is, you get put straight through on the fone when u ask. the tivo is very sensitity to signal levels if u have correct level u should be fine. mine was -14 at the highest level. and my pictures was terrible on every sd channel now it very good. can't fault virgin media the engineer checked the signal round the house to make sure it wasn't my end. he come next day with a splitter that increased the signal level to -7/-8 which has improved picture drastically i was made up i can watch tv without picture break up now it sorted now tho for how long nobody knows.

I wonder if people (including me) are seeing variable SD channel PQ due to a more limited range of acceptable signal level with Tivo, whereas the V+ was more tolerant with a wider range of signal level able to generate a high quality SD picture?

Can the VM Tivo team remotely inspect your Tivo set up to see how you are set up as I feel it could be useful if VM could inspect customers complaining of lower SD PQ to see if there is a trend? Maybe worth a call to the Tivo suppport team for them to check my settings?

My installer was a last minute backup to the planned installer and while he had Tivo training, his background was BB installs as we talk more about the super hub than Tivo. I just wondered whether he did set up everything correctly? He did install an equaliser to be fair which indicated signal levels were checked.

With adjustments to my TV, I've managed to improve SD PQ but watching a game of football on BBC1 SD on Sunday morning, indicated SD still cannot give me the same quality I had with V+.

The V+ let you see the signal level, but I can't see the same on the Tivo.
My levels were high on the V+ and I don't recall the installer doing any checks.

I had the engineer back to checkout my TiVo because of poor SD picture quality. He confirmed levels were OK and could find no problem. IMO the SD picture quality on the TiVo is simply dire. That's how it is.

The signal level has nothing to do with it. It's the TiVo itself

It can't be, else everyone's picture quality would be dire. I find mine is very marginally softer that is all, mostly on poor quality broadcasts, i.e. British Eurosport 2. I certainly can't say it is dire, or anywhere near it. Watching MotoGP on BBC2 yesterday, the PQ seemed every bit as good as it was on V+.

The problems people are experiencing may be specific issues to them, i.e. they way TiVo was installed, the quality of the feed into their house, their TV, the set up they have with regards to passing the picture through Amps etc.

According to TiVo signal strength and snr is important to picture quality pixelisation and macro blocking:

Why do you say it has nothing to do with it?

No it's not, it's the way the TiVo upscales otherwise hd would be 'softer' too. I noticed from the second I installed the TiVo that the picture was more blocky.

Because my snr is in it's 40s and I have every type of attenuator at my disposal.

Re: TiVo Picture Quality
 
I'm quite happy with my SD picture.
Quality depends on the bitrate, and the BBC, for example, is very variable.
On the V+, the BBC varied from almost HD to VHS.
Same on Tivo.
Funnily enough, I find most of my viewing is in HD. Didn't realise it until I got the Tivo.

Re: TiVo Picture Quality
 
Your comparing signal break up which affects all boxes, this thread is comparing the TiVo to the v+ sd picture quality with the same signal
