Poor picture quality vix 4.2

[kryton]

Thanks Andy but already tried that.
The GUI restarts ok but as soon as you open the EPG or a menu the box crashes.
Thinking of selling and going back to VU.

Okay mate. You can't go wrong with the Vu+ Solo2, still a great receiver imo. The Mut@nt HD51 looks interesting too.

Am I right in saying that running the commands...

 echo 1 > /proc/stb/vmpeg/0/pep_block_noise_reduction 
 echo 0 > /proc/stb/vmpeg/0/pep_block_noise_reduction

actually fixes the problem?

Yes mate i think they are the commands within the script.

Arnt these settings also what the video enhancer plugin changes? They do work but having to run them each time you wake the box from standby is a pain in the......

... but adding them to a cron job doesn't work?

What did you put in the cron job?

i don't think iskin will work on an image less than 4.2.
4.2 has stuff in it to make skin fully functional.

It does work but you can only do it in minutes and as i understand its minutes past the hour?
So if you set it for 10 minutes then its executed at 10 minutes past every hour....
So sometimes after bringing the receiver out of standby you had to wait for the cron to execute the script.

I have tried setting it so it runs every 10 minutes with */10 * * * * but this doesnt work.
Ive been trying to see modify the standby.pyo to execute the script when exiting standby....there was a tutorial on a site...but that didnt work either.

... but the skin is just the GUI and won't affect the actual picture quality, would it? The on-screen graphics may look better but it's hardly going to fix the video stream? I'm puzzled as to why MPEG block noise reduction is being set in the first place and presumably this script just turns it off?

Its not the skin thats the problem mate. The vertical lines appear with any skin set. I was just trying to see if i could use the new iskin thats in the 4.2 feeds as im having to use 4.1.

Theres a thread here relating to the issue, i think aido explains the noise block reduction better than i do: http://www.world-of-satellite.com/sh...ent-seems-like

To be honest, I don't think cron is suitable, there's a file called /etc/rc.local which is run at system boot.
You'd be best waiting for someone to confirm that that's the way to proceed, or that I'm talking rubbish.

That's why I posted, in case someone is chasing the skin as being a solution to "Poor Picture Quality ViX 4.2" which is what this thread is about, no? The problem lies deeper within the video handling or with some interaction between the image code and the driver. I thought I had noticed a similar quality issue on some SD channels on my Quad Plus but I can't reproduce it.

The script does run from boot mate. But once the receiver is put into standby (not deep standby) then woke up the lines are back and the script or video enhancer plugin have to be run again. Which gets a bit tedious.

No mate the thread was about the same PQ on the et10k.
Its just gone off topic a bit in places.

Someone may have been trying something similar on OpenPLi (a long time ago)...

Thanks mate, this is the 1 i found after an extensive google search.

Got the standby.py source from github

Edited it the way that tutorial shows you, put the standby.py into the lib/python/screens folder and rebooted the box.

After a reboot the vix menu was missing and when trying to access plugins i got a warning saying "some plugins are not available, cannot import devbuild"

I replaced the standby.pyo with a back up but it was still the same so had to reflash the box.

But this is pretty much the thing i want, if i could get it to work.
