Thema: discontinuity On Skynet Solved For Ever?!

[sepehr]

Hi , i wanted to ask gurus and other people who know solutions for overcoming discontinuity problem share their ideas so i can decrease discontinuity to zero.I use skynet for offline data download
I have a 90 cm dish and a switch with 2 plugs (first for hotbird and second for W3 at 7E)
the only transponder which my skynet starts downloading is:
# OpenSky w3
tuner=11299000,H,13500000,A
pids=

is that normal? should it work on other transponder of w3 too?



please tell me ANYTHING which could possibly create discontinuity  and what to do to avoid it<<

thanks in advance

--Hardware Info
3.8 AMD 64 bits CPU
256 Mb of VGA
2 GB of Ram
main board: Asus SLI M2n32 Delux
dvbcard : skystar3(made by geniatech Co)

well, lets start

other transponder should work also, please decribe the problem a little bit more: no signal or no download?
my location is tartous/syria, so maybe you have weaker signals on your location.
you can try for example:

# w3 evolve 
tuner=11554000 H 27500000 A
pids=

here you have only one pid, just check if you still .discontinuitys.
Disable all other freqency/pid-entrys !  reason: some pid-streams are somehow garbled, they create those discontinuitys.

and about your mentioned frequency: my signal is 40%, quality 100% dish used 2,2 m, no discontinuity, at the time being only the pids 3*1*-3*1* are active.

i can download but as discontinuity goes to 300 or higher after 3 or 4 hours i can't download large files and they become partial,
so you say that anytime i want to start downloading i should check active pids? Pids i mentioned are usual ones and i usually don't edit them.
that can cause discontinuity?

although evolve (tuner=11554000 H 27500000 A) works for my in skygrabber it doesn't work in skynet(it doesn't start downloading)!
does it mean that my dish is not set?

here is a pic of my dish configuration:


Ps: could you introduce a stand alone pid scanner software?

[pogo13]

did you changed the tuner frequency in skynet.ini?

Yes

[pogo13]

maybe you can use the data application, you got with your satcard. add the provider and pid in the app and see on the level. If the light is green, start skynet and end data app.

yes i have done that, worked for some but not for (tuner=11554000 H 27500000 A)
and any ideas for discontinuity problem?

[Chrisse]

It might be possible that parts of the data are not streamed via Sky, instead those packets are transmitted to the recipient via the necessary modem connection. Therefore no way of easy capturing this data is given.

Thanks guys it downloads now!,i had to restart pc(don't know the reason)
and now please help i have discontinuity  problem,what should i do?

[pogo13]

discontinuity ist a never ending story.

with some isp you cannot clear this problem, see above the answer from Chrisse.

a lot of us (skynet user), use a separate pc for grabbing. because any other soft can interrupt stream and you will get discontinuitys. how specific it is, you saw wit your 11544 MHz problem, you had to restart your system.

some of us have overclocked our sat cards to minimize discontinuitys.

i read very often in russian forum (i think the bigest one). there are thousands of opiniens to this problem and no one 100% solution.

how ever, keep grabbing... and good luck of course

i have bought a new pc for data grabbing,could you give me some tips to overcloak mine?

Tuning your PC does't helps. pogo means: speed up your SS2 with this:

2 things:
1.is there an english version of this?
2. does it work on SS3(made by geniatech)?

Well give translation a try 

How to speed up your SkyStar 2 card

1.   Why?

The Sky Star 2 DVB card is quite often used for grabbing data streams provided via sky. Technisat, the manufacturer, quotes a symbol data rate of possible 2-45 MS/sec. The card is clocked by an integrated 45 Mhz crystal oscillator which provides enough bandwidth for most of the providers. Grabbing Data for more than one recipient seems to interrupt the transport stream (ts) resulting in data loss. The idea to speed up that SS2 card was created by some russian freaks. Changing the crystal oscillator to a 50 Mhz type lead to an enormous decrease of data loss. Data loss was brought down to virtually zero by using a 66 Mhz crystal oscillator.

2.   What will we need to do so?

First we need a crystal oscillator providing a 60 Mhz clock (costs: 2 to 5 ? (the ?german? Radio shack´s like Reichelt and Conrad)) . The offered Oscillator by Reichelt not only is cheaper it has even the same shape than the original mounted one. Using the Conrad type, which is slightly bigger in size, will make some extra work necessary such like extending the pins with some wire. As tools we will need a soldering iron, solder and flux (usually the flux is contained in the core of the solder).  For the ease of desoldering using a desoldering pump will help (from 2,95 ?).

Important: Don´t forget to touch a piece of metal (water pipe, heating) to get rid of any static electricity before working with the card otherwise you risk permanent damage of the card.
You must not (don´t do) heat the parts for more than 3 sec in one go whilst soldering or desoldering otherwise you risk permanent damage to the parts.

3.   Step by step

The crystal oscillators are build with 4 pins. 3 Pins are used one is nc. To determine proper placing one edge of the housing is not rounded as well as it is marked by a dot on top of the housing.

First you will have to desolder the original crystal oscillator. Keep in mind where the marked edge was lockated. Using a same shaped osc mount and solder it the same way the original was. Using the bigger sized type you will have to lengthen the pins by soldering wires to them. Due to the multilayer structure of the board it is necessary to solder both sides of the pins (up and down). Finishing this step you are done!

Remount the card in your PC! P&P!! (Plug and pray  )

4.   Will TV work?

After changing the oscillator there will be no TV picture, thus the data reception seems to reach the optimum. To solve this problem use a piece of Veroboard and mount both oscillators on it. GND and CLK pins will be connected together and with short wires connected to the ss2 card. With a little switch and some wires you can determine which Oscillator will be switched on. To find out the according pins you will need the pinout of the oscillators, if u are used to do such work this might not be the problem, if u are not used in working with electronics I would recommend to find somebody who is, to give you a hand.

thanks alot, I'll give it a try! hop i don't mess with my dvb card
