ET10k 4x hybrid tuner issue

[ccs]

Yes, no issue using 4x dvb-c/t2 tuners, found issue is using 4x dvb-c tuner, using hybrid tuners should be fine.

I bought an ET10000 with 4* DVB-C/T/T2 tuners from WOS about 2 months ago.
I checked that I could record 4 programmes on 4 different mux's, and mistakenly assumed that 4 red roundels in the recording list confirmed it was working.
Unfortunately, this is not the case.
To cut a long story short, the recording on tuner C fails when the 4th mux is selected for recording .
A switch to live tv on a different mux can hit Tuner D
So no more than 3 recordings work on different mux's, and only 2 if the m/c boots up on a mux not about to be used for recording.

Currently using OpenVIX 3.2.003

A tuner box which came with the ET10k has written on it.......

(Note) for ET10000 only

1. Please do not install a tuner that requires a CAM at Tuner4 slot.
2. Please do not install the DVB-C tuner modules at Tuner3 and Tuner4 at the same time.
3. At case of using 4 different cable signal, pleas use 3 DVB-C modules and one DVB-C/T/T2 module as below.

- DVB-C at Tuner1, 2, 3 and DVB-C/T/T2 at Tuner4.
- DVB-C at Tuner1, 2, 4 and DVB-C/T/T2 at Tuner3.


A bit clearer than the manual, and surely this suggests that four DVB-C/T/T2 tuners should be ok.

Attempts to access the failing mux give the error "service not found (SID not found in PAT)".

I've created a log file if it might help.

I set preferred tuner to C to prove that tunerC does initially work ok.

The sequence is ....

Watching bbc1, record bbc1 (uses tunerA), record itv (uses tunerC), record yesterday (uses tunerB), record drama (uses tunerD).

At this point, tunerC (The Jeremy Kyle Show, sorry!) stops recording and the mux is unavailable.

All recordings started from the epg using the record button.

Another log with a slightly different outcome.

It's the same sequence as before, but instead of recording drama, I went to bbc HD live tv, via the epg. (ie different mux again.)

This created the "service not found (SID not found in PAT)" error for tunerD and a blank screen.

TunerC had also stopped recording, but the second switch to bbc HD via the epg worked ok (tunerD).

How are your feeds connected? Are you using a splitter, booster/distro switch or loop thru?

[ccs]

I'm using a variable gain booster, selecting zero gain, with 4 outputs feeding the 4 tuners.

The SNR is 50% +/- 5, the tv/another pvr report 100% quality on the same feeds, and there is no picture breakup.

I've not had any recording failures apart from the one's I can generate every time.

I've tried a variable attenuator but this made the SNR drop even further.

[ccs]

The only other thing I can think of is Open Webif reports the current channel details as DVB-S2, DVB-C and sometimes DVB-T.

Maybe the tuner type really is getting mixed up?

[ccs]

I've tried with OpenVIX 3.2.004, with no settings or plugins, same problem persists.

One more possible clue, the original sequence was ....

Watching bbc1, record bbc1 (uses tunerA), record itv (uses tunerC), record yesterday (uses tunerB), record drama (uses tunerD).

This crashes TunerC.


Watching bbc1, record bbc1 (uses tunerA), record itv (uses tunerC), record yesterday (uses tunerB), record Ch4 (users tunerC), record drama (uses tunerD).

(ie 2 recordings on tunerC.)

This crashes tunerD.

I guess I must be the only one with this particular configuration.

Something else I've noted which may be related.

After doing the "tests", going into deep standby gives the message "Recording(s) are in progress or coming up in a few seconds! Really shutdown now?"
There are none, so I say yes and 2 minutes later it switches back on again.
Powering off again, and it goes straight into deep standby.
However, the box still misbehaves later in the day, and 2 mornings this week it's been switched on when it shouldn't have been.

Maybe these "phantom" recordings are part of the original problem, taking up tuner slots??

I don't normally delete recordings and timers while they are still active.

Is there anything else I can try/do? Being limited to 2 mux's out of 4 is not why I bought the box in the first place.

I've tried strace, but it fails with a ptrace error (something to do with uid's, I think).

Mine is hybrid slot abc, sat in d no problems here make sure tuners are configured after swaping them about I did have some trouble when sat was in slot a but been fine after swapping a and d around

Open ports?

I've got 4xhybrid dvb-c/t/t2's. They all work ok individually, so I guess they must be configured ok.

Open ports?

Sorry, you've lost me.

If you mean ftp/telnet/openwebif, then no (I'd already tried testing again this morning before posting earlier.)

I can access the box via windows explorer, which I had opened this morning, but I hadn't opened any network links.

Surely this wouldn't explain why the box switched on again 2 minutes after going into deep standby?

Are you able to record on tuners a,b and c and then record on tuner d?
Mine appears to work, but viewing the 4 different mux's confirms that (usually) tuner c has stopped working.

Yes run on the timers every week and if i manually do it to sfill the same iv not got a preffered tuner set either
