Hi,

I could do with a little bit of help...

Whilst this is a UK forum and concerns allot of UK topics, my problem is actually with a setup in Thailand. Saying that, all the AV equipment I am using I have bought from the UK.

Setup is in a sports bar in Bangkok. There are two broadcast inputs, one from a large satellite dish showing the South African networks and the other is from Thailands cable operator UBC (they also do a satellite version but we have the cable version).

The satellite feeds come in via Coship CDVB5110D receivers then into a newly installed Onyko TX-SR 876 amp. From there it goes to a Epson TW 3800 1080p projector and out onto a 11ft wide screen painted with Goo paints, again all bought from the UK.

When it was first installed the Thai installer used a simple panasonic DVD upscaler with DVD drive to allow all the connections to be fed in through one HDMI cable to the projector, but I recently replaced that machine with the Onkyo amp.

Unforunatly, despite fiddling with every possible setting the Onkyo the overall picture was worse with judder and motion blur occuring wheras before it was not present. Yesterday we removed the Onkyo and put the Panasonic back in, the picture quality instantly improved.

So, my question is, from the very limited info I have supplied above, does anybody have any idea of a suitable upscaler that could actually improve the picture quality of the projector output? Money is not an issue, but I need to get it right this time as i'm unable to return the product if it doesn't do the required job for obvious reasons.

I am also using a HDMI repeater as the HDMI from the cable the amp to the projector is 20m long - strangely this works fine with the panasonic but resulted in the blue screen of death when used with the Onkyo!

Any input would be greatly appreciated!!

Just to confirm...You did put the amp in pass through mode for video?
Also,what is the model number of this DVD player that works?

Hi Gordon,

I'm 99% sure I put it on "Through" mode, I tried every option available in that menu several times - overall the picture was worse than before.

The Panasonic model is DVR 560H. That and the Coship are the only two main bit of kits I bought from Thailand, so I have very little idea of what they do in terms of the rest of the system.

Just been watching the athletics tonight and the picture is back to where it was before I changed to the Onkyo, which is not that bad for a projector of it's size with the feeds in this country, but as usual I feel it could be improved.

Most of the time the picture is very good, but when you get into far off shots of sports or fast action things don't look so good. Players in football lack definiton at distance and there is a level of motion blur on the faster moving shots.

I'm kinda thinking this may be as good as it gets, but i'd love to be able to really get it looking sharp, anything other than that will mean admitting defeat, which i'm not keen to do...

Cheers,

Tom.

Well if it goes weird in pass through then somethign is up.

However, if there is no real pass through then it could be that the Silicon Optix chip in the Onkyo is doing stuff which the chip in the pvr/dvd isn't. My guess would be that the SO chip is trying to do clever motion processing or 3Dnoise reduction and that is what is causing the smearing effect. The DVD/R probably doesn't have that sort of stuff in it.

There are scalers that will make the image cleaner and more detailed but the costs are probably way above what you want to spend.....ie £1000 +

Hi Gordon,

No that's fine, I can live with that - I will be in touch tomorrow.

I own an Onkyo 876 and it doesn't do any NR processing or the like if you tell it not to. Have you tried enabling "Game Mode" to cut processing to a minimum?

Are you sure the problem isn't a case of different resolutions being sent (perhaps 1080i from the Panasonic and 1080p from the Onkyo?) triggering different memory banks in the projector, one having the offending processing turned on and the other not?

I don't think I tried Game mode, it didn't seem relevant, i'll give that ago. The only problem with that though is that it's not doing what I bought the machine to do!

I tried every different resolution many times, it didn't seem to make any difference at all. Sorry, just to clarify as well I'm not using the Panasonic and Onkyo together, it was one or the other.

Cheers,

Tom.
