TV Server Error on Fresh Vista Install (1 Viewer)

[offbyone]

Hi, I've used MediaPortal on many PCs so far and installed without Problems.

This time I have set up a fresh Vista x64 SP1 install and tried MediaPortal setup which runs fine, but the TV Server won't start.
(Actually the Service is running says Windows but starting the config tool it asks to start the service and fails)

The error log keeps saying that there is a NullReferenceException in TvLibrary.Implementations.TVCardCollection.DetectCards()

Any idea what I am missing?

SQLServerExpress2008 is installed, working and the DB was successfully created.
MY TV Card works (I confirmed with ProgDVB).

I've looked up the source code what happens in DetectCards(), but that is alot of stuff. Can someone send me the pdb files, so I can tell you the line of code where it is failing, or is there a way to get the full exception text, not just the message?

I taken the lates code from svn and compiles the TVServer and Plugins to get the Debug files. I replaced the files on my system with the ones I compiled and I did NOT get the error anymore
But I still can't get it to work, my card is detected now, but when doing a scan, it says no signal on all transponders... (I confirmed that I have signal using ProgDVB).
The attached Logfiles show the scan and one error when starting up the service:

2008-12-16 19:27:26.425687 [TVService]: Exception : System.BadImageFormatException: Es wurde versucht, eine Datei mit einem falschen Format zu laden. (Ausnahme von HRESULT: 0x8007000B)

Please any help from the devs?

Ok after compiling the TVService was running as 64 bit, I recompiled for x86 and now I get the error again.

it is in the file TvLibrary.Implementations.TvCardCollection.DetectCards() line 118:

if (devices.Length > 0)
      {
        ITuningSpace tuningSpace;
        ILocator locator;
        IFilterGraph2 graphBuilder = (IFilterGraph2)new FilterGraph();
        DsROTEntry rotEntry = new DsROTEntry(graphBuilder);

        //DVBT
        Guid networkProviderClsId = typeof(DVBTNetworkProvider).GUID;
        IBaseFilter networkDVBT = FilterGraphTools.AddFilterFromClsid(graphBuilder, networkProviderClsId, "DVBT Network Provider");

        tuningSpace = (ITuningSpace)new DVBTuningSpace();
        tuningSpace.put_UniqueName("DVBC TuningSpace");
        tuningSpace.put_FriendlyName("DVBC TuningSpace");
        tuningSpace.put__NetworkType(typeof(DVBTNetworkProvider).GUID);
        ((IDVBTuningSpace)tuningSpace).put_SystemType(DVBSystemType.Terrestrial);

        locator = (ILocator)new DVBTLocator();
        locator.put_CarrierFrequency(-1);
        locator.put_InnerFEC(FECMethod.MethodNotSet);
        locator.put_InnerFECRate(BinaryConvolutionCodeRate.RateNotSet);
        locator.put_Modulation(ModulationType.ModNotSet);
        locator.put_OuterFEC(FECMethod.MethodNotSet);
        locator.put_OuterFECRate(BinaryConvolutionCodeRate.RateNotSet);
        locator.put_SymbolRate(-1);
        tuningSpace.put_DefaultLocator(locator);
        ((ITuner)networkDVBT).put_TuningSpace(tuningSpace);

the last line throws the error, any idea? I don't have any DVB-T device...

I changed it to only detect DVB-C card and now it's working.
Maybe you should put a try catch around the detection of each card type?
In my case the variable networkDVBT was null a giving the exception!

Hello

Im using swedish Vista 64 bit (MCE with Tv pack 2008) and I seem to have a very similar problem, it may be the same problem but I dont want to make any assumptions.

2008-12-23 18:11:20.195061 [TVService]: Exception ystem.NullReferenceException: Objektreferensen har inte angetts till en instans av ett objekt.

"Objektreferensen har inte angetts till en instans av ett objekt."= Object reference has not been set to an object instance

I just bought FireDTV C today, installed to get it working in Media Center (which works fine). I then wanted to try Media Portal since I want to use both my analog tv tuner and my FireDTV which I have read I can do in Media Portal but not in Media Center, and thats when I got stuck when starting the Tv-server.

I think that FireDTV reclassifies the device as DVB-T instead of C just to get Vista Media Center to accept the device, could this be the reason that the exception is thrown?

I'm getting the same error message when I try to start the TV Service!

I'm also using a (german) Vista x64 Home Premium SP 1 with a Technisat SkyStar 2 HD DVB-S2 Card (which works fine with DVBViewer).

On my other PC (Vista x64 SP 1 Ultimate) the TV Server works (no error) with a Technisat external USB DVB-S Box ("SkyStar USB plus").

On both systems I'm using SQL Server 2008 Express.

Hi,

I'm seeing a problem that looks very much like the one described above. Problem description and logs seem to match (didn't compare full logs thou)

I'm using Vista x64, service pack 1 + TV pack 2008. I've two Technotrend C-1500 TV cards.

I'll post full logs if needed. Right now I need to take a break

Hi,

I think I've solved my problem. I disabled 4 Services related to Media Center and TV Server started working.

It wasn't enough just to stop the services, as they restarted again.

Hi!

Hm... I disabled the following services: Mcx2Svc (was already disabled), ehRecvr, ehSched and ehstart - but the problem remains. Which services did you disable?

The (for me) strange thing is, that the MediaPortal tv service is listed as "running" in the Windows services manager - but if I start the TV Server Setup it still tells me that tv service isn't running and asks me if I want to start it now - and if I choose yes - I get the permanent "TV service not startet/running" error (NULL reference exception etc. in the logs).

Maybe it's related to the TV Pack 2008 (on x64) - because on the machine everything works fine I never installed the pack (and never used the Windows Media Center anyway).

Hi,

I disabled the following services
Mcx2Svc (Windows Media Center Extender Service)
ehRecvr (Windows Media Center Receiver Service)
ehSched (Windows Media Center Scheduler Service)
ehstart (Windows Media Center Service Launcher)

I think I disabled this one as well (or it was disabled already)
WMPNetworkSvc (Windows Media Player Network Sharing Service)

I've no idea which one helped. However, the problem seems to come back every time I reboot (The services above stay disabled, so disabling them helped only so far).

The (for me) strange thing is, that the MediaPortal tv service is listed as "running" in the Windows services manager - but if I start the TV Server Setup it still tells me that tv service isn't running and asks me if I want to start it now - and if I choose yes - I get the permanent "TV service not startet/running" error (NULL reference exception etc. in the logs).

I can get around the problem you mentioned by stopping the TV service manually and then starting the TV-Server Configuration utility. It still tells me that tv service isn't running and asks me if I want to start it now - and if I choose yes - it doesn't complain anymore about TV service running. Instead the program throws following exception. TV service starts anyway and I can watch TV after that (until next reboot)

I'll try some combinations and take the logs later. That will probably be on Thursday or Saturday.

Hi,
You're all using bda drivers(required for MP) for your card & not fake drivers(which some tuner manufactures have made) so MCE can use it?
