is there any news about that topic? Did anyone find a solution? Also Orange @Atlantic Bird3 5W 11471 V 29950 2/3 8PSK suffers this problem.

[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).

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.

He did it few months ago. If you're on latest than you should have it.

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.

It was quite not appreciable on my part to provide a fix or reply in
time nor spend much time on it earlier, but that said i was quite
stuck up with some other things.

Can you please pull a copy of the multiproto tree
http://jusst.de/hg/multiproto or the v4l-dvb tree from
http://jusst.de/hg/v4l-dvb

and apply the following patch and comment what your result is ?
Before applying please do check whether you still have the issues.


BTW: lot of patience you have compared to the other users :)

Manu,
I've tried to increase those timers long ago when played around with my card
(Twinhan 1041) and scan utility.
I must say that I've concentrated mostly on DVB-S channels that wasn't
always locking.
I didn't notice much improvements. The thing that did help was increasing
the resolution of scan zigzags.
I've sent a patch on that ML and people were happy with the results.
The patch went to Igor's repository, don't know were it goes from there.

I believe DVB-S2 lock suffer from the same problem, but in that case the
zigzag is done in the chip and not in the driver.
Since I have no documentation of the chip I was stuck and left it. So if you
have the knowledge or documentation of the chip,
try to go in that direction.

By the way, question to those who have such channels:
Does windows based applications show those channels properly?

With regards to the zig-zag, one bug is fixed in the v4l-dvb tree.
Most likely you haven't tried that change.

I did look at your patch, but that was completely against the tuning
algorithm.

Along with the patch i sent, does the attached patch help you in
anyway (This works out for DVB-S2 only)?

I use Igor's version, but he merges v4l changes quite often.
Can you point me to a patch or code that was changes? I want to make sure I
have that fix.

Well, you know, it works :)
What is the algorithm? I didn't make major changes beside increasing the
zigzag resolution for different scan stages and zigzag around the frequency
that previous stage was able to detect instead of starting from the
beginning. Sounds logical to me.

I didn't tried to watch any DVB-S2 channels yet, not sure I have any FTA
with my current directions.
But I'll try that change later for scanning.

BTW, too bad the code has very few comments inside to understand all the
numeric values used for calculations.

- From what I understand the driver still has some issues. Got feedback
from another guy with Canal Digital in Norway that he has the same
issues as me.

Not sure if the diff was an attempt to fix the digital artefacts but I
tried applying the diff manually on the source I grabbed from
http://jusst.de/hg/v4l-dvb/ but did not notice any improvements or
difference with the artefacts. Would any logs be helpful?

If there is anything else I could try I'm willing to try it out. I
appreciate your effort. Thanks.

Manu,

I've tried both multiproto branches you indicated above, *with* and
*without* the patches you sent to the ML (fix_iterations.patch and
increase timeout.patch) on this thread.
Sadly, same behavior as S2API V4L-DVB current branch. No lock on 30000
3/4 channels. It achieves a 0.5 second jittery sound but no image. It
seems the driver is struggling to correctly lock on that channel, but
doesn't get there in time... Or maybe the hardware... Dunno...

Channels like

ASTRA HD+;BetaDigital:11914:hC910M2O35S1:S19.2E:27500:1279=27:0;1283=deu:0:0:131:133:6:0

work just fine.

But channels like

simply don't work.

BTW, I think the channels above that don't work have a 0x0B stream
indication. Satellite operators are misleading on the stream (h.222)
when in fact they are h.264. Read that were on the ML. Don't know if
it affects anything, but hey... I have to try everything! ;)

I'm available to any tests necessary to fix this once and for all, if possible.

Just let me know.

Thanks for all your hard work.
