View Full Version : [VU+ Duo] pixelation even on fta channels worse on hd channels
This is a weird one, I keep getting pixelation on my vuduo box, I am on the latest vix image. my signal strength is 90% and my ber is 0. My sky box from the same dish is perfect. Its only recently started to happen since I put the latest image on. Could it be a driver issue and has anyone else experienced this issue. The poland vs england game was that bad I had to watch the match on freeview. I have swapped over the HDMI cable still an issue. (i hope its not my TV). This might be my next test to swap the TV's over
cant say as i have encountered any problems like this, and the last drivers issued for the Vu's were in august so i doubt that could be a factor.
thats what I thought my
SNR = 90%
AGC = 93%
BER = 0
Could any of the above readings be causing the pixelation. It occurs once every 5 minutes or so but the signals dont really deviate much from the above settings.
I think my TV may be on its way out. Either that or the vuduo.

BER is always zero as no VU-STB supports outputting BER-values.

Since when do you have this?
Do you use CCcam?
i have had this since installing the latest image,,, cccam is enabled but the pixelation even occurs on FTA
Try an earlier image to see if the problem is there aswell

the new or old images are not the reason for this problem, if it were, there would be masses of simular threads
the problem is local to the orig poster,
and most likely the problem is with the dish/coax or lnb
or at worst, a corrupt image

I have no idea what you call 'the latest image'......
There is a problem in CCcam in build 374 that can cause just this problem. That should b fixed in build 378.
Ok thanks for all your responses but I issue is now resolved. I will share with you my experience since it could happen to someone else.
Sorry maybe I didn't explain myself well enough when I say latest image I was referring the latest VIX image with the latest software updates. The Pixelation only starting happening since I performed a software update and it was getting worse every day.
The only things I installed extra were the following
enigma2-plugin-cams-cccam.2.3.0_1.0_mipsel.ipk
enigma2-plugin-cams-mgcamd.1.35a_1.0-r3_mipsel.ipk
enigma2-plugin-extensions-autobouquets-e2_0.4_mips32el.ipk
Magic-HD Skin and Open Pli skin.
I tried turning off CCCAM and MGCAMD and the pixelation still occurred. I also tried restarting enigma and also full reboot and the pixelation still occurred. This was happening for a number of days every 8 minutes or so I would get a pixelation.
I went out to my dish and swapped over the connections on My LNB and the pixelation stayed with the TV downstairs, I swapped over my HDMI and leads and the pixelation stayed with the TV. I swapped over the TV's from upstairs to downstairs and the pixelation stayed with vuduo.
I was about to re-install the image again but then it was resolved by turning off the VU_DUO leaving for 5 minutes and turning on again. The box had never been powered off since the VIX OE3.0 was released (2 months or so ago). So I guess It must have had some sort of memory leak when an update was performed.
I have attached a couple of screen shots 1 of the pixelation and 1 of the signal strength.
Hope these comments helps future users who may have similar experience. 2031520316
sorry for hijacking
i have the same problem using a cable tuner
checked everything seems my 52 inch lg plasma cant cope with the hd as its pixellating bad sd is no better
when i change this to a 32 inch its picutre perfect
seems to be a problm with the lg abdd cable
i have tried almost everything and im unable to resolve
just move my recordable to a smaller tv

Nothing to do with your TV whatsoever. Will be your cable setup.

i have tried absolutely everything and seem to think the tuner in the venton unibox needs adjusting

I've had the same problems with my vu+solo. no such problems on my zgemma h2h on the same setup. Initially I was told to buy a signal attenuator. I did and it fixed my issue for a long time but I've just recently updated to the latest Vix image and my problem returned. I have been able to fix a lot of the channels affected by re-adjusting the attenuator however some channels will not come good no matter how much I tweak it. on the positive side most of the worst affected channels are also available in HD and playing fine on that method.
When it comes to VM cable, the signal does vary across the frequency band and if you don't have a TV sub, they are more likely to move your tap around in the street box to allow them to fix a signal problem with another subscriber. Your signal can go down or up at any time.
I have been this very similar issue with my vu+ duo2 also that i think you had. I have noticed that the SNR is jumping around.
I have noticed that if I run a speed test on a device connnected via wifi (my iphone) then it glitches a lot during the download but becomes completely frozen during an upload.
As soon as the speedtest is finished the picture comes back. This is the the same for FTA channels also.
Something on the line is causing glitching when the internet is being used for downlaoding/uploading/streaming.
The annoying thing is that when I connect the VM box I can't see the issues, even if I start downloading/uploading so complaining to VM is not getting me far lol.
What I know for sure is that if I remove the LNB that connects the router to the splitter so it's only TV there are no glitches and all is well so it's definitely something VM have done. Possibly an update or other change in thier infrastructure for my cabinet/area.
Any ideas what this could be or any solutions to this yet?

Have a strong signal on my box for cable, BUT...found pixelation lots of times if box moved, seems the cable going in only has to be moved slightly for it to start playing up for me, not done so for a while as never touch it, so look at this?

Took a while but finally figured out whats causing the glitching for me.
I have a nice strong signal coming into the house. This is then split into 2 cables (One for the router and one for the VU+ box) The cable that goes to the VU+ is quite long (about 35m) and the power level at the end of the cable was the right level. so all good here.
The problem was that the cable that goes into the router is short (about 30-40cm) and so the power levels remained high and were too high into the router.
This is why when the router was using high amounts of data speeds (especially upload) it was causing noise on the line overall and causing glitching.
We have now but an attenuator on the split that goes into the router. This has reduced the power level going into the router without reducing the power level in the VU+ and now there is zero glitching.
As a test you can use a speedtest app on a phone connected to your internet. If the glitching is a lot more severe during the download/upload part of the test then you most likely have the same issue.
I hope this helps someone :)
