The following Problem occurs when recording with my Xtrend ET-9200: If you record a broadcast and you Switch to another channel while recording and then Switches back to the Station currently being recorded a Picture interference (pixelation) will be shown. When you then watch the record exactly the same Picture interference (pixealtion) will be shown! In other words the record is useless because it isn't free of errors. Please note: It does not matter if the broadcast is encoded or not.

At first I thought  it was up a problem with the hard drive, but after I've tested various hard drives, I can exclude this. It must be due to OpenPli or better how OpenPli manages records.

I heard that it is related to LNB. With some LNBs this problem occurs with some not. Afaik it's not a OpenPli problem.
I think here in the forum was also a discussion about this problem.

Hi,

this mainly happen when you have a Twin-, Quad- or Octo-LNB with bad power supply. I never heard it from people with a multiswitch with it´s own power supply.

 

What LNB do you use?

Hello!

 

I use 4 different LNBs and with all this LNBs the interference problem occurs. INVERTO Black Ultra Quad LNB, a SMART Titanium Edition TQS Quad Switch LNB, a MTI AK54-XT2N Quad LNB and a INVACOM QDH-031 Quad LNB.

 

I think all this LNBs are high Quality LNBs and I don't think the Problem is realted to poor power supply.

If this should be the case, than because the power delivered by the XTREND ET-9200 is to poor!

 

Please note: With all this LNBs the interferences occurs!

 

For your reference: My Buddy ​uses QUATTRO LNBs with a SPAUN MULTI - SWITCH and he has exact the same problem!

Definitely the LNB. It even happens when another receiver connected to the same LNB changes channels.

Hello!

 

I'm sorry but I doubt this very strongly! If this were the case, than you have to explain to me why this happens with 6 different LNBs ( and I assure you all of them are top - quality LNB's like INVERTO BLACK ULTRA,  MTI AK54, SMART TITANIUM Edition). And please note 1 antenna System uses 3 QUATTRO LNB with a SMART 17/4 Multiswitch and the other antenna System uses the same LNBs but QUAD with DISEQ Switches. Further I tested this with two different XTREND ET-9200 boxes (on 1 ET-9200 I swapped the powersupply to be sure, that no problem with the power supply is present). I than used an old Topfield TF-5000 to check and oddly enough , there are no such problems with this receive on both antenna systems!

So therefore it seems irrefutable to me that the problem has to do with the manner in which records are managed by OpenPLi.

[betacentauri]

I don't have these problems with my et9200. So I don't think it's an OpenPli problem.

I've got a Global Invacom LNB on my 1.8m dish. This is considered a quality LNB. When I change channel on the Solo2 there is temporary disruption to the image on the Ultimo. Possibly caused by the DiSEqC switching signal.

Hello betacentauri!

 

What channels are you looking at ? Do you watch encrypted channels ? And whom so, what channels and with what Softcam?  Have you ever tried to record a station and repeatedly switch to other stations an back again to the recorded channel while recording? Have you tried to do so also with encrypted channels?

 

I doubt this!

Hi,

 

yes, I watch and record encrytped channels. I have no problems. Never experienced any picture interferences. Well, there are some because of other reasons, but not related to channel switching. I'm quite sure about it. I use cccam.

[betacentauri]

Just tried it again. I started record of Sky 3d. Then I switched to several fta channels and other encrypted SKY channels. Then I stopped the recording. Checked the recording and there are no issues.

Hello betacentauri,

 

What equipment do you use on your satellite system​, I mean what LNBs and what MultiSwitch or Diseq Switch? Which HDD?

 

Greetings

 

[betacentauri]

Hi,

 

it's a ST2000DL004 HD20 (2TB HDD). I use ext4. It's important that you have formatted the HDD in the box. How big is your HDD? But I don't think it's a HDD problem, because channel switch has nothing to do with the HDD.

LNB, Multiswitch I cannot tell you, because I'm living in an apartment building. So it's not my satellite dish, MultiSwitch and I have no access to it. I can only say that I have 2 sat cables and it's no unicable.

 Hello betacentaury!

 

Could you please try the following: Record an ecrypted Sky channel, during record Switch to other encrypted Sky channels and than back to the channel being recorded. After that please check the record for errors.

Thank you in advance for your help!

PS. Which ccam version are you using?

Edited by teleradio, 19 August 2015 - 16:53.

These issues are usually caused by cross-talk in a low-budget switch or a monoblock type multi-LNB (which has a built-in switch). Some people seem to have this, regardless of the box brand and type used.

Hi,

 

This has nothing to do with recording. You can also reproduce it by enabling the PiP and zap.

Hi teleradio,

ok, this time I have recorded encrypted channel and switched to 2-3 other encrypted channels and then back to the first one. Then stopped the recording and checked it. Recording is fine. No issues at all.
I use 2.3.0.

[Erik Slagter]

Here the same, I have a multiswitch (wich powers the LNB's, instead of the receiver) and I never see these problems.

[teleradio]

Hello!

 

The problem with interferences when switching between different transmitters and back again while recording has been finally solved.

I could not believe it, but it was both the Spaun multiswitch and the Spaun - Diseq switches which were inexplicably defective​!

 

I have replaced the defective switches by two 17/8 Multiswitch of MEGASAT and now all the recordings are perfect again!

 

I want to thank everyone here in the forum, for their valuable hints and tips!
