Re: DM 800HD se clone

hi sjamesamuel

perhaps a bad cable -> can you try with another one? ; is there a switch on the back 'HD YPbPr or SCART RGB'? if yes, try changing it

Re: DM 800HD se clone

Interlace problems (perhaps): if the flickering appears in the edges (top and bottom) of horizontal lines. But with new tvs, this effect is nearly zero.

Yes, it's exactly as you describe it, on horizontal edges.
Is it a problem with the box?
Can it be fixed?

I use a converter from scart to A/V and then an A/V cable. I tried changing the cable, but it was the same.

Re: DM 800HD se clone

hi

did you check all possible settings of the stb and the tv's - surely the video display settings?

Hi
Yes, I tried playing with most of them, but there are some options that I don't understand.

Scart (fbas or rgb) means 576i.
So you will defenitly have this flickering. What do you mean with a/v converter? Do you use a modern flat-tv?

Is it possible to use a hdmi-cable with 720p or 1080i? Then the flickering is (normaly) over.

I use something like this to convert scart output of the receiver into A/V for TV:


The TV I refer to is CRT TV.
On HD TV it works properly without any flicker.

Re: DM 800HD se clone

I think you have problem because of editing the skin file.
Maybe something went wrong, maybe you made a mistake.

Try to use a skin with the proper aspect ratio for your tv and I think that your problem will be solved.

This defenitly means fbas-signal with 576i, and even some modern tvs have problems to display this signals without flickering.
The reason is the (often poor) deinterlace hardware for those signals because they are optimized for hdmi and hd signals.
Flickering with this adapter is not a failure of the receiver - you will have the same result if you use an original dreambox or a 40 Euro lowcost-box.
And real hd-signals are impossible with this.

So what do you suggest to get it to display properly on this TV?

... the pic relates a AV IN, so

you should consider to use an AV OUT

Re: DM 800HD se clone

@sjamesamuel: with that hardware there's nothing you can do against it.

I've an older sd-receiver which also has only an analogue-scart exit. I've connected a dvd-recorder with hdmi-exit between receiver and tv.

receiver -- scart -- dvd-recorder -- hdmi -- tv

In the dvd-recorder I use 720p as signal to hdmi.
Result: a much better picture quality at the tv and no flickering.

Do you have the chance to change to hdmi?

Re: DM 800HD se clone

Actually the box has an HDMI output which works properly with HD TV. I am trying to get it to work properly with non HD TV.
I played with settings in the A/V setup. Some settings like 480i removed the flicker altogether, but the image size and quality wasn't good.

"with that hardware there's nothing you can do against it."
Do you mean scart or A/V ?

Re: DM 800HD se clone

... I am trying to get it to work properly with non HD TV.

Sorry, but under this condition it sounds like: mission impossible!
An older "non ht-tv" only supports 576i or perhaps the last ones 576p.

Perhaps 576p can help. But normaly the av-output has 576i. Only the old analogue y c b - three cable output had 576p.

Re: DM 800HD se clone

Which output option should be used in this case : Scart or YCbCr ?

I also noticed that NTSC 60 removes flickering, but the image isn't good enough, even when setting the TV.

[Satphoenix]

Re: DM 800HD se clone

@sjamesamuel: for (possible) deinterlace defenitly use ycbcr. I don't have a dreambox, but I think the dream has this. Then you can switch in the settings of the box to 576p - if your tv can work this signal.

Ntsc60 means other picture frequence, but lower picture resolution - loss of picture quality - not to recommend on "normal" not-ntsc tvs!
