Signal probs...Please help

[gazaman]

Hi all.
First post here so be gentle
Ive just got a clone DM800HD running Enigma 2 Dream Elite blackhole 1.33d v3 sim 2.01
I have a problem with some HD signals.
Most channels work perfectly fine without an in line amp but a couple are unwatchable. When the in line amp is connected, the previously unwatchable channels are now perfectly fine but some of the ones that were ok are now glitchy now and again.
Has anybody encountered anything similar?
Any help would be greatly appreciated.

Thanks
Gaz

The inline amp doesn't always do the job.
What tuner do you have fitted?
How good is your channel 4 HD?
Also if you are using a server for your premium channels, the problem might be that.

Thanks mate,
Channel 4 HD is perfect. Channel 5 HD and sky Comedy HD seem to be the worst (Ones with the lowest SNR)
Not sure on the Tuner. Its as standard.

As long you snr is above 50%, it should be Ok. If your box is a 800pro it should have the latest rev M tuner, and shouldn't need the inline amp as you would be getting around 99%. I assume your box is older with a earlier tuner, and sometimes the inline amp helps.
I would speak to the guy who provides your connection, see if he can give you some help.

Ok will do mate.
For example,Sky comedy HD has snr of 63% without amp but 51% with....but if I dont have the amp in I cant get certain channels.
I dont know if its related but the RAM usage seems quite high at 97%, is this normal? The signal seems to break when viewing EPG etc, almost as if the proccessor is struggling.

The flash memory at 97% shouldn't affect the signal, but it will make your box sluggish. Hopefully it's just down to plugins. If so remove any that you are not using. Most importantly, if you are using cross epg/picons, make sure they are on a pen drive in one of the ports on the back of the box. If they get aimed at the flash memory, it can be permanently dammaged. I have a box now that will not take a image larger than 45mb, because 25% of the memory has bad sectors.

Thanks again,
I dont really use any pluggins to be honest so I could remove them all. Are any essential to the box or can they all be removed? Off the top of my head there is: Youtube,webinterface,spinnerselector(or something),original dreambox,modem and a couple others.
I have a HDD installed and programs record fine etc but I noticed yesterday that in Device manager>Mountpoints it says that the HDD isnt mapped. Is that right?
I have tried using crossepg but for some reason when i choose the provider then press yellow to download now,I get the green screen followed by a reboot. So I currently download rytec epg everyday and this is sent to the hdd.

Don't remove any of those plugins, you don't have that many. Also it needs some of them for the box to function. In the cross epg configuration, make sure it is set to load on to HDD/USB stick. preferably USB stick, because if you aim it at the HDD it will be constantly running, producing unnecessary heat. If it gives you a lot of green screens, it might be best to reflash and start again.

You could try flashing a open pli image this is a bare bones image with nothing special in and it runs very smooth on my 800 hd clone doesn't even flicker when I'm checking the channel guide like some other images do

It wont matter if the EPG is stored on a USB flash drive or the HDD as when accessed once it is then stored in the RAM memory and each time you access the EPG afterwards it comes from the ram and not the HDD or USB pendrive

The epg data ammounts to approx 13mb s*y uk, if you aim that at your internal memory, chances are if you don't have that space. It will cause a green screen loop, and you will need to reflash to remove it.

Hi mate,

I think we may be getting crossed wires here the EPG as you say is best stored on either a USB or the Hard drive, But once it is accessed by the receiver it is then stored in the RAM and not the internal flash which means either the USB stick or HDD are accessed just the once only and not again unless the receiver is switched off to standby or restarted.

So when you say if its stored on the HDD it causes more heat because you access the EPG frequently thats not true its only accessed once and then thrown into the RAM so the USB or HDD can go back into sleep mode or whatever.

The only reason we store Picons on a USB is because these are permanently accessed all the time so if stored on the HDD this would spin constantly every time you changed channel.

Hope that clears it up.

Cheers chaps.
I think my epg is pointed at the hdd so that should be ok.
Do I need to do anything with the mountpoint or is this completely unrelated? For the hdd it says unmapped.

You need to map it as the default location for EPG is internal flash, If it keeps losing its mountpoint have a look at another image.

Thanks mate,
Sorry for the questions but i'm new to all this.
So, just to confirm I should save EPG to flash memory?
I can do this no probs.
Is the Mountpoints option that is in device manager a completely different thing then?
I'm a bit confused!?
Epg save location is set in the EPG menu but there is an option in the main menus to map the hdd as well which I'm unsure what to do with.
