I use the latest version of ProgDvB (5.15) Its the first time I try out this software, so it is possible, that I missed something with the setup or configuration.
My OS ist Windows Vista (no service pack installed) on a Medion Box. The TV driver is recogniced by ProgDvB as {BDA} 713x BDA DVBT Tuner 1.53.

So the problem is: No channels are found at all! But as said: Level is Hight, Quality is zero. Media Center SW works, so I guess it is no hardware problem.

Any idea what might went wrong?

Try to tune a transponder manually.
The MediaCenter software might tell you working transponder parameters, to put into ProgDVB's 'search transponder' menue.

Normally, ProgDVB uses transponder list files for scanning. But it's possible, there's something unusual on your local situation, like frequencies or symbol rates. So perhaps it maybe necessary, to edit a suitable file.

Thanks for your reply.
I found the "Scan Transponder" dialog and it shows Level 80% Quality 0% there, too. So I went through all Transponders (C5 - C69) without any change ...

any other ideas?

Thanks and regards
HoM

In real life, on your location, only a couple of transponders will be in use.

Transponders are not just frequencies, but they have several individual parameters, that are essential for reception.
Confirmed working parameters are to be found by looking into channel parameters of your original software,one channel on each transponder.
Write down that parameters, like exact frequency, symbolrate, modulation.
Then try to put in that parameters into ProgDVB manually, by use of 'scan transponder' dialog. You may have to click into the (empty) results field, to execute changes.
Watch L & Q change, hopefully...
If getting a good Q value, scan.

thanks again.

I went to my SAT box in the living room (cause I did not find the parameter in the Microsoft Software :-/ )
Freq 11836 /
Inversion Auto /
Symbol Rate 27500 /
Pol. horicontal /
FEC 3/4

In the scan transponder dialog I can edit the Frequency and the Symbol Rate (the values given were of a completely different order of magnitude ! The frequency that is originally in the dialog is more then 10 times higher, Symbol rate is lower).

However: With these two values I tried "lock" and "scan" (not exactly sure, what these do) but no change...

the values I enter never get stored :-/ I have to edit them every time I enter the "scan transponder" dialog, so maybe they dont fit ...

Hi,

I have some channels now !!

Somehow I got an entry in the Diseq Settings ( I guess it was with "Add LNB") where I could select ASTRA 19.2 and with that quality and level are both at 100% ! And many channels are found.

One painpoint still: ARD and ZDF do not show picture, so not play sound. other channels like Pro7 do well ...

regards
Holger

Now I am getting completely confused...

Ch 5 - 69, this is DVB-T.
Astra 19.2, this is satellite.

So, do you use a hybrid tuner?

ProgDVB cannot control different tuners within the same hardware.
Maybe it's possible, to either initiate the -T or the -S component, by use of the adequate BDA device.
However, DVB-T and DVB-S use completely different frequencies, data rates, modulation types, ...
So you must enter satellite transponder parameters if using the DVB-S device in ProgDVB, but terrestrial data for a DVB-T device, of course.

A well working transponder list for Astra 19.2 comes with ProgDVB, but probably one for your local DVB-T services won't be there.
There are some inside for DVB-T, but one of those may have to be edited manually, to suit your local situation. That's what you need the precise parameters for, which could priorly be tested on a manual transponder search.
If you can't get them from the original application, you may also find them on DVB-T pages on the net, Start looking on the site for your local ARD station or here:
http://www.ueberallfernsehen.de/
(if it's Germany we're talking about)

However, we are talking on digital logics.
So precision and details are required.

On almost every DVB software, you can find the parameters of a transponder and a station on it by checking the channel properties of that station, once it already is in the channel list.
Terrestrial TV uses frequencies between ~ 45 - 850 MHz, relatively low symbol rates, a bandwidth switch (7 MHz for VHF or 8 MHz for UHF), and a guard interval. Not all parameters are required to be entered for every hard- and software
DVB-S uses GHz frequencies, like 10700 MHz to 12750 MHz for Ku band, and it has different switches and options.

So DVB-T and DVB-S parameters for the same station MUST be different, and both are different from analogue or digital cable or analogue satellite.

ProgDVB can control different tuners on same card. But not all hardware support using more one tuner at once.

Hallo Jürgen,

you are right, the tuner is a hybrid! I forgot to mention - sorry - because I only use SAT and there is no DVB-T available in my area.

So it seems that the configuration I found out about last night "told" ProgDVB to use the "right" (SAT) portion of the tuner and thats why I have some programs now. I will continue investigating, why some channesl - like "Das Erste" - do not work.

However this was a huge step and thanks again for your support.

Best regards
HoM

OK, you've found the DVB-S device.
So now let's try to proceed:

Do you have an exclusive cable to the LNB or multiswitch?
Or are you running through an LNB loop back of another device or a simple splitter? This would mean, the tuners can't work independently, on band and polarisation switching.

Did you scan the channel list you're using, or did you get it from somewhere else?

Do you have good level and quality on the ARD and ZDF transponders, like on the others?

If yes, do you have valid video and audio IDs in the channel properties of that stations?

Even if no picture, try to record a sequence in .mpg, watch file size rise. Then play back somewhere else, like in your DVD player software.
If that works, you have some codec related trouble in ProgDVB. Perhaps try the codecs from your DVD soft.

BTW, do you get (real) 16:9 and 4:3 picture elsewhere?
ARD and ZDF are on 16:9 permanently.

Whatsoever, there must be a logical reason for your problem with ARD and ZDF.
So go very systematical

To answer your questions:
I have a 4x LNB but I use only 3 of the outputs: 2 go to my dbl -Receiver in the living room and one goes to my computer. There are no issues with my dbl Receiver.
The cable goes directly to the computer and there is no other device looped or in any other way connected.

I did scan for the channels, yes. For ARD I got a slightly different frequency then I found at http://www.pirmasoft.de/astra/das_erste.htm. But correcting the 500kHz difference did not change anything.

Level and quality are both at 100% for ARD. above and below ARD are some strange trash channels like "das erotische TV" which have very low quality values and show no picture or corrupted picture. I will not miss these channels, I just thought it was worse mentioning.

The VPID and RCRPID are as mentioned on that web page I mentioned above.
Aspect ratio ... difficult. I guess WunderWeltWissen, now running on RTL2 is 16:9 .... Can I ensure that somewhere?

Again thanks and best regards
HoM

Your idea was very good: I recoded a sequence and ... there is picture and sound in good quality! What does that mean?
And I found that there is EPG info, too !

Best regards
HoM

after this recording ... the channgel worked and ZDF too. How can that be? Veeeery strang, but ... not bad

lets see, if it works after a restart of progdvb ... Yes it did. So dont know why but things seem to work now!

regards
HoM

Now let's talk technical...

ARD is available from
Astra 19.2°E, named "Das Erste", on 11837 MHz H 27500
and from
Hotbird 13°E, named "ARD - Das Erste", 11604 MHz H 27500

The strange adult channels are on the Hotbird transponder, which is owned by RTL. You will also find ZDF on that RTL transponder, plus DW-TV and swiss RTL stations.

On Astra 19.2 you will be on an ARD only transponder, shared with a few other ARD stations. ZDF is on 11954 H 27500 there.

So make sure to be on the correct satellite with your LNB and dish...
An Astra listing won't help on Hotbird, nor would the wrong transponder list selected in ProgDVB.
Good listings (to compare with) are to be found at satcodx.com, transponder files at joshyfun.peque.org (Technotrend .INI format)

BTW, the aspect ratio flag is visible in ProgDVB from 'File' --> 'Property' (= Decoder info), on live TV.
On playback of a recording, most players also have file properties or video parameters somewhere.

p.s.
As you just wrote things are go now, you must have solved some codec related problems as well. So check all the audio / video (DirectShow) settings and write them down for 'just in case'...
