Hey Guys

I've just upgraded to a Plasma and now Sky suck (shock I know) so I have changed the scart to rca to scart to component but its not really any better, if anything it maybe slightly worse?
I'm not sure if there is any other settings I should be changing in the advanced settings but I set it for component and also changed it to widescreen, I see the strength is good but quality is not that great, its a Motorola but unsure of model.
If anyone can point me in the right direction of any info on settings etc I should check, firmware etc that would be great, not interested in paying more for MySky just want to get something abit better than what I have now.

As it has been pointed out before on this forum, you have found out how bad the Sky picture quality actually is.
With a nice new big screen TV this quality becomes more readily noticable.
They compress the signal a lot to save on satellite bandwidth.

The only way you will get a better picture is with MySkyHDi and the HD ticket but even then, that only covers the channels that are in HD, all the rest will still look the same.

Sky are only concerned with their sports and movies customers. The rest of us who are into news and other general entertainment basically don't matter, and get their channels compressed to all buggery.

I know MySky is going to give a better picture but I also have been told composite is meant to be better than rca's and it doesn't seem to be, I'm not paying more for MySky so just need to try and work out why the picture isn't really improved by going to component.

Garbage in, garbage out. Component just gives you sharper garbage with luminance and chrominance components kept seperate, similar principle to not washing certain items of clothing that leak color with whites.

Yeh the signal isn't great but when I don't have movies its a waste of money to get a MySky to only get HD on 2 sport channels.
The new TV is great, movies and my PS3 look sweet but its abit of a headache when it comes to TV, before I had the aerial coming into the sky box then to a splitter to tv and the other through an amplifier to the other tvs in the house, all were CRT so not issues with picture as all same format, now with the Plasma in the mixture I either have to have the sky box set to 4:3 centre and get full screen on the CRT's and a sh***y pic on the Plasma or 16:9 on the sky box and then get the mixture of 16:9 and 4:3 on Sky and lose full screen on the CRT's.

One thing I wasn't sure on was when you change the aspect on the sky decoder between 16:9 and 4:3 how it effects the signal the CRT's down the line, does changing this change the format they will on 1,2,3,4 and prime on the coax or does it only effect the Sky broadcast?

Will have a play with the aspects etc tomorrow and see what the best setup is but at the moment I've played with so many settings I think I'm TV'd out and can't work out what I've done or not done so if the above is not making alot of since just put it down to burn out 8-)

If you have a 16:9 TV and Sky then the only correct aspect ratio setting is 16:9 nothing else, and ensure that the TV is in 16:9 mode as well. As has been documented in this forum in the past the main network broadcasters (TVNZ, TV3, Prime) transmit full time in 16:9, never anything else, if they are playing out material that was captured in 4:3 then they will pillar box it into the 16:9 frame, hence blackbars to the side, this is the correct way to view it.

As to component being worse than composite, as has been mentioned this is commonly the case due to Skys low bit rates on the basic channels, and the TV1/2 feeds that actually come from TVNZs FreeView transmissions are probably the worse ones, Sky Movies and sports channels normally dont look too bad.

Things to check however is that all the noise filtering options are on low or turned off, and the sharpness is mid to lower on its scale.

The built in freeview signal is great so not issues there as I'm not using 1-2etc via Sky, have been through and swapped back between composite and component and the component seems to be better so must have just been a bad broadcast I was watching when I changed it over. 

I never remembered having the black bars until I had a TV that doesn't have them, I know some movies etc where but don't remember the other shows being like it, I was sure it was normally full screen on 1,2 etc and maybe me changing the settings on the sky box to 16:9 had changed the signal to the old tv's as it does come into the decoder then out of the sky decoder to a splitter and amp back to the other TV's in the house but I disconnected the decoder and had the signal going straight to the old TV and it still has the bars? I starting to  think I had gone mad as I was sure I didn't have the black bars before but I connected one of the old TV's directly to the antenna removing everything else from the loop and its still the same, CTV still in full screen but 1,2,3,4, prime are all letter box and sky fed back though the coax is slightly out of aspect since its set for the plasma's 16:9, am I missing something as I'm sure my old TV's where showing the picture full screen but now letter boxed but how can that be even without the decode in the loop??

So many changes I can't remember what I was like pre Plasma which doesn't make it easy, looks like I need the old TV's to display center cut but they aren't anymore, or they weren't to start and I am mad 8-)

Don't you think it is logical that given the fact that TVNZ/Mediaworks transmit fulltime 16:9 on digital services that they would alter the analog transmissions slightly to allow viewers to see more picture width. 13:9 letterbox look has been like this for nearly 2 years on TV3 via PAL BG analog transmissons.

Your TV has to sample the analogue signal and convert it to digital to display on the LCD. If you use component then it has to sample 3 signals. If you use composite then it has to extract it to 2 signals, chrominance and luminance, before sampling but it is only 2 signals to sample and not 3 so less work load on your TV. But composite looks worse as you loose quality when all the signals are combined into one. S-video on the other hand is chrominance and luminance. So see if you can get s-video out of your Sky box. You can with the small silver Pace box, which is what I use.

You can never have enough Volvos!
