Hello,

I got a Technotrend Budget S2-3200 card and is using Canal Digital in
Norway. Channels are found on;
http://www.telenorsbc.com/templates/Page.aspx?id=399

It seems that I got all the DVB-S channels working fine.

Nat Geo HD and Histoy Channel HD are the only two HD channels I can
lock, and I have problems with digital artefacts, lines across the
screen missing data and tons of errors from the frontend. See below for
error log.

MythTV does not find Discovery HD at all while some other HD channels
only get partial lock.

I'm using kernel 2.6.28 with
http://mercurial.intuxication.org/hg/s2-liplianin

mythtv from http://svn.mythtv.org/svn/trunk/ with all the patches from
http://svn.mythtv.org/trac/ticket/5882

I've also tested http://linuxtv.org/hg/v4l-dvb with the same results.

Hi Jonas,
just guessing - try another card slot. If there are more devices on one IRQ
the transfer speed from the card can be lower and causing problems at
channels with higher bitrate. I had similar colision between PCI network and
sound cards. When I moved one card to another slot, the problem was solved.

Regards,
Tomas

Re: [linux-dvb] Technotrend Budget S2-3200 Digital artefacts on HDchannels

[Newsy Paper]

the transponders you don't get lock are problem transponders of s2-3200.
The driver is still not able to lock on dvb-s2 30000 3/4 transponders :(

Which software do you use to play HD content?
you need either xine-lib 1.2 with external ffmpeg (recent developer's version).
or xine-vdpau (if you have a NVIDIA graka that supports h264 hw acceleration).

regards 

Newsy

[linux-dvb] Technotrend Budget S2-3200 Digital artefacts on HDchannels

[Newsy Paper]

the transponders you don't get lock are problem transponders of s2-3200.
The driver is still not able to lock on dvb-s2 30000 3/4 transponders :(

Which software do you use to play HD content?
you need either xine-lib 1.2 with external ffmpeg (recent developer's version).
or xine-vdpau (if you have a NVIDIA graka that supports h264 hw acceleration).

regards

Newsy

I can confirm this. I use S30W (Hispasat) and one of the providers,
Meo, broadcasts everything on DVB-S2 30000 3/4.
I can't get a lock on any of the transponders/channels. And to make
matters worse, not even scan-s2 can get a really usable channel list.
I had to build the list by hand, according to
http://pt.kingofsat.net/pack-meo.php page.

And it still doesn't work.

I use vdr-xine and xineliboutput with vdr 1.7.0 and up, plus
xine-vdpau to no avail.

What's the point of having a DVB-S2 card if we can't tune to those
channels? What's missing in the S2-3200 drivers?

What drivers do you use?
I saw that Igor did some changes in his repository to lock on high SR
channels.

I've tried with both v4l-dvb and Igor repository. Haven't tried with
latest changes Igor made.

I'll try it tonight and comment on the state.

But for now, I'm somewhat disappointed. It's been over 6 months trying
to make DVB-S2 transponders to work and no result to show.

But wey... DVB-S works perfectly.

Latest changes I can see at
http://mercurial.intuxication.org/hg/s2-liplianin/ were made about 7
to 10 days ago. Is this correct? If that's correct, then I'm using
latest Igor drivers. And behavior described above is what I'm getting.

I can't see anything related do high SR channels on Igor repository.

It won't. All you will manage to do is burn your demodulator, if you happen
to
be that lucky one, with that change. At least a few people have burned
demodulators by now, from what i do see.

I don't know if the drivers or not but my card (TT S2-3650 CI) broke,
got my money back
from the company and i ordered a Tevii S650 from Germany which will
arrive this week.

What are the symptoms of burned demodulator? How can someone know if its
still ok?

Does your mantis driver work ok with such channels?

Manu, would you be so kind to explain why it will burn the demodulator?
It happens only with 30000 transponders? And only with this card?
Does this mean I can't use my card to see channels on 30000 transponders?

Chris

Regarding the documentation the demodulator is designed to run at max. freq. 
99MHz. Some series of demods burn when the freq is set above this value. But 
this value is enough for most of transponders with SR up to 30000.

Some Russian transponders have SR 43500 - so the demod is set a little bit 
above 3x of this value. This could be dangerous.

This patch (or change) doesn't solve the problem with SR of 30000 and FEC 3/4 
or 5/6.

BR,

Ales

The first time i saw it was that the DVB-S2 demod was returning no
carrier. After some time it was stating timing error for DVB-S as
well. Finally it all ended up with demodulator I2C ACK failure, and
eventually a frozen machine after a week (my test boxes run throughout)

Touching the demodulator, i happened to have almost a burned finger.
I wanted to know whether this was a single case. During the
development phase, i did mention it to Julian about this, since he
was the very first person to test for the stb0899 driver. He
jovially laughed about a burned demodulator and a finger, left his
machine on after i did some tests on it. Eventually he too had the
same results. Finally we changed cards.

I don't have such channels. Tested with a max of 27.5 MSPS

What frequency did you use to burn it?

I didn't see anyone here on the list that reported a hardware failure so
far.

By the way, Igor returned the chip frequency for 27.5 channels to 99MHz and
raised it a bit for higher SR channels, so there is no danger for majority
of the users.

It was a long time back, don't remember. It has nothing to do with
the frequency of the transponder, but just the master clock. You can
run it to a maximum of 108Mhz overclocked, 99Mhz to be safe and
sufficient.

May god help you. I didn't know that you knew more than the
demodulator manufacturer !

Ok, be happy with his change and keep quiet. 135Mhz is out of bounds
of the hardware specification. You are on your own. Raising the
master clock, doesn't bring you any advantage.

>From your statement (and the patch), it is clearly evident that you
don't understand head or tail what you are stating or patched the
code for:

For a lower sampling frequency (aka Symbol rate), you need a higher
clock and or higher time period. For higher sampling rates (Symbol
Rates) the the master clock has to be decimated to  avoid overflows

This implies the patch to increase the master clock for acquisition
at a higher symbol rate was utter nonsense only.

All i have is to say:

Alas !

Sorry, an error in one part. ^^

For a lower SRATE, you need a lower clock and a longer period of
time. With a higher SRATE for the same coeffecients, you are bound
to overflow, unless you decimate certain register contents.
Recalculating those register values are quite tedious and lots of
calculations involved for a different master clock.

The result with a higher master clock (with the same coeffecients),
if you happened to see some positive results, it was the result of
some overflow or underflow, which is for sure.

Please speak for yourself, I never said I know more than a manufacturer.
I wrote a fact.
Intel also rate their chips and everybody overclocks them to crazy ratings.

Did someone overclock you as well?
Chill out!
It would be better if you'll be more productive instead of quieting people
who try to help.

Again, I'm commenting facts. As I saw from the reports the overclock seems
to help with the problem.

So be so kind, and add comments to the code you write so everybody could
find its head and tail when trying to fix bugs.
It is clearly evident that you don't really want that someone else will
understand your code.

Again, facts are that the patch help and make the device more stable for
DVB-S channels.



Oh well, I hate that I had to get so low with my message, but that's that
happen when someone try to align with your expressions.
In case you didn't know, you're not alone in the universe, get used to it.

I am writing just to share my experience with tt3200 drivers. The
following are just observations about the behavior of my card:

1. The card has never tuned reliably with the v4l-dvb s2api driver or
the multiproto driver. This concerns not just high rate dvb-s2
transponders but also some plain dvb-s transponders as well. And this
is not just random hiccups but consistent behavior. German Eurosport @
19.2e is a prime example.
2. When Igor first increased the high clock to 135MHz, there was a
marked improvement. All of the tuning issues were gone. However I am
using a rotor and the higher clock rate somehow broke rotor control.
3. Next Igor backed down the high clock to 99MHz and introduced a
"very high clock" of 135MHz. Tuning went back to unreliable. Rotor
control was ok.
4. I bought a hvr4000. And now all of my issues are gone.
