1228973 2011-09-05 10:52:00 Yes, TV #1 is connected to a DSE Freeview HD box with EPG and TV #2 /Projector with Play TV (Not as good quality).

The connection on TV #1 at the wall is not connected properly (Sky guy again :( ). When you move the connector a bit, the signal will go and TV will display 'Check Cable' or Similar. It's just not connected properly. Could that be the cause? And on TV#2 the wall socket is connected by 2 cables from the roof to one jack.

Can post pictures if needed.

1228974 2011-09-05 11:03:00 The reason why you dont get ghosting is because the encoded signal is decoded using error-correction (removing extraneous information (multipath signals/ghosting)).
When the signal is weak the parts of the code necessary for reference to correct frames would be missing (blocky=digital = snow=analogue).

Sahilcc7, Try this if you want to improve your signal strength, bigger ones are available, (might pay to check your aerial/wiring too if its a few years old), get a competent aerial installer (not a "sky guy").

1228977 2011-09-05 12:43:00 Sounds to me that you need the connections looked at, the signal leaving a splitter is the same strength on all output ports and should only be weaker if there is a longer cable run or a bad connection, disconnecting outputs doesn't affect the signal strength on the remaining ports, in fact in some designs they work better if all ports are terminated. The amplifier should have enough output strength to split several times usually.
Assuming there are wall plates you could take them off and check the connections yourself. The common connector in use in NZ is not a great one, and cheap ones use crappy screw terminals that dont always make good contact. The central wire needs to make good contact as does the braid or foil screen and they must not be in contact with each other. A short circuit on any port will affect the signal on all.

Yup that thread confirms what I am saying.
The amp improved the picture quality on the Prime analogue signal.
It also improved the freeview hd signal as they were getting dropped frames, which is not a picture quality issue.

1228979 2011-09-06 06:30:00 Must be the longer cable then. And is the Maori channel HD? To watch RWC games on. That might be fuzzy because I think its still analogue. sahilcc7 (15483)
1228980 2011-09-06 06:33:00 I think the only channel that's 1080p is 3.One and 2 are 720p. The rest are 576 Speedy Gonzales (78)
1228981 2011-09-06 07:01:00 I've just installed a 91 element aerial to improve our signal strength for tv and PVR. We're using digital freeview. Freeview on the tv was good but the PVR was pretty marginal pixelating at times(mainly recording times!!) The difference to the tv is quite noticeable in HD(I would say perfect) and the pvr has become quite acceptable. We are in a marginal area for signal strength. Unless you are in a high strength signal area with a good aerial I would try running your setup on one tv and see what you get. If its good you know everything works(so far) Just add the other tvs one at a time and see if they are acceptable. A lot of cables are not put together properly, the end connectors need to have the central wire soldered into the pin to have a pretty permanent solid connection, If your signal is not strong, using an amplifier on three tvs would be pretty marginal I would say.

1228982 2011-09-06 08:22:00 Checked out the Play TV today and it TV 1,2,3 were great. HD picture. The others were freezing at times but watchable. That was the problem - just the analogue channels. Don't really care about it, RWC will be on the HD channels.

Thanks guys.
