Another 'no channels found' post I'm afraid

[tomhanman]

Hello All,

 

I have just purchased DVBViewer to try and, well, view DVB channels!

Here in France we have some SD channels and some HD channels, all free to view. I have an aerial on the roof with an amp up in the loft feeding a cable that drops down to behind our telly (panasonic plasma with freeviewHD (called TNT-HD in France) mp4 tuner built in). Here there is a 4-way distributer which feeds the TV and my three tuner cards. Well the TV works fine, but I can't get anything through DVBViewer, not a single channel, nada. The tuner cards show up no probs - Avermedia twin tuner and Gigabyte single, and after loads of scans etc, nothing doing. The 'signal' counter goes up to about 75% on each channel scanned, and the PAT remains yellow the whole time, with no channels at the end. I've chosen France, and none in the transponder list to no avail. I have no idea about choosing the 'group' and the instructions seem to date from a version of DVBViewer from another age and only discuss DVB-s tuning.

 

I know from my TV and a French website that my DVB channels are as follows:

 

Transmitter: Toulouse Pic du midi

channel	center	video	sound

22	482	479,25	485,75
26	514	511,25	517,75
36	594	591,25	597,75
48	690	687,25	693,75
50	706	703,25	707,75
54	738	735,25	741,75

 

My tech:

 

Running Windows 7 32bit

Mobo is asus p5e-vm hdmi

video card ATI 3650 with latest ATI catalyst control center and drivers 10.1

tuner card 1: Gigabyte Hybrid TV card driver version 1.3.3.1 (05/12/2005)

tuner card 2: Avermedia A177 PCIe dual hybrid driver version 1.3.0.76 (05/06/2009)

Please someone tell me I've forgotten to push the great big green button right in front of my face!

 

Thanks,

Tom.

and a French website

Please provide a link.

 

The table above (I made it more readable) doesn't tell me to which frequencies DVBViewer has to be tuned. You may want to try the "Terrestrial (EUR)" list, or, if it doesn't work either, TransEdit (download from the members area). It allows to edit transponder lists, to enter/change frequencies and to try if scanning them gives results.

Bonjour Tom

 

I use TNT from Carcassonne ( Pic Nore ). I had lots of problems until I got a file ( I think it was from Griga ) called france.ini

DVBViewer PRO now works with a Technisat stick and a " no name " stick.

 

( in 2005 we chose DVBViewer because you can record TNT subtitles - very important to us not being French )

 

2 months ago I bought and installed WIN 7 Ultimate : The Media Center finds all TNT channels without problems, it shows / records subtitles and has a very easy to use timer function. Furthermore it is easy to stream to our SONY Bravia.

 

Hope this helps...............

Thanks for the replies, but I think I have a bigger problem.I really don't understand the situation but I also run Win7 and MC either tells me that there is no signal, or there is no tuner, or the signal works then breaks up after a while or sometimes it works perfectly! No way to understand it, the signal is always fine on the TV, so what is happening inside the computer? Is something causing interference? I have just updated the drivers for both tuner cards as I have found new W7 drivers on the manufacturers sites, and now its even worse... AverTV can't find anything either, nor Media Center.

 

I can't believe that both of my cards have a problem, so is it possible that the computer itself doesn't like watching TV? Or do the PC tuner cards that we buy have a much poorer sensitivity than the tuners in qality TVs?

 

I can't find the site that I got those frequencies from. But I'm not sure it makes much difference as the problem doesn't seem to be with my tuning, or with DVBViewer, but with my luck! But I don't quite understand why you can't just ask the program scan the whole sky - find any broadcasts out there, without limiting it (and risking errors) by trying to direct it to certain frequencies.

 

I've only got one other pc with a PCI slot so I'll try and install the Gigabyte tuner in that and see if I get and joy, although its an atom board so I don't imagine its going to like the HD transmissions. But no way to check the Aver card as its PCIe and this is the only mobo I've got with PCIe.

 

Thanks for the ideas. and Velling... learn French, then you won't need the subtitles, or otherwise only watch the american series which are often available in 'version original'

Or do the PC tuner cards that we buy have a much poorer sensitivity than the tuners in qality TVs?

You can be pretty sure of that... and also more sensitive to signal neatness.

As you probably heard around, digital signal problems are very hard to check out whithout professional instruments and it's so easy to have different signal neatness on different outlet... I've similar aerial (amp + 4-way) and despite all my effort I have 4 slightly different "buouquet" on the 4 appliances (2 TV and 2 PC stick on four different and distant outlet).

This is much more true if your region is in "switch over" phase because analog signals greatly disturb digital one and they are trasmitted with much more RF power; since my region "switched off" (=all analog trasmission on TV band are ceased...) there was a great improvement, but still there are noticeable differences even on the two identical PC stick...

 

But I don't quite understand why you can't just ask the program scan the whole sky...

That function isn't normally needed (and very time consuming) and you better do it with Griga's TransEdit: read here how to "Blind Scan"...

Gioxy,

 

Thanks for the reply. I'm not sure if it makes me feel better that others suffer similar troubles or not!

Interesting that we have similar aerial setups... although my four outlets (3xtuner cards and 1xTV) are all on leads that are 24inches long straight out of the Four-way adaptor, and I even invested (not very much) in those screw type aerial connectors everywhere to give good contact and shielding. I have swapped the cables around to try all of them in each input and it makes no difference, the TV wins!! Have you tried that to see if its your cables/routing that are upsetting things?

 

 

I'll have a go at TransEdit later on. With my fingers crossed, although I fear spanners and hammers may be required to solve my problem. I prefer hammers.

Of course they are! ...sorry if I don't make this clear before, but even a simple turn more can make difference within two cables...

But don't mix this up with the difference of sensivity/quality of reception between different tuners: I also have got a third (well, the first I buy) PC stick (made by Pinnacle) I can't use because no matter in whichever outlet I link it, it cannot tune the main public TV transponder (whose freq is 490 MHz, so nothing special) while I have no problems on same transponder with the 2 other stick (Terratec)... also between the 2 TV set there are slight differences that depends on the cables but also on the two different tuner they have (one is on-board while another is a cheap external top-box...)
