I am having problems watching and recording a channel at the same time. When i do this i get the following error in the error.log:

2009-04-23 18:23:51.518242 [6]: Exception   :TvLibrary.TvException: Unable to tune to channel

and the following output in tv.log:

2009-04-23 18:24:02.411242 [6]: dvb:SubmitTuneRequest  failed - removing subchannel: 3

I can't find anywhere what the 0x1 resturn code means. All return codes i can find are much longer than 1 (0x0088aa or something like that).

To further investigate this I downloaded the source and debugged it. I traced it back to this piece of code:

Log.Log.WriteFile("dvb:Submit tunerequest calling put_TuneRequest");
        int hr = ((ITuner)_filterNetworkProvider).put_TuneRequest(tuneRequest);
        Log.Log.WriteFile("dvb:Submit tunerequest done calling put_TuneRequest");
        if (hr != 0)
        {
          Log.Log.WriteFile("dvb:SubmitTuneRequest  returns:0x{0:X}", hr);
          //remove subchannel.
          /*if (newSubChannel)
          {
          _mapSubChannels.Remove(subChannelId);
          }*/
          throw new TvException("Unable to tune to channel");
        }

I than changed it to try and ignore the return code 1, and than it worked, it tuned to the channel just fine. I used the following:

Log.Log.WriteFile("dvb:Submit tunerequest calling put_TuneRequest");
        int hr = ((ITuner)_filterNetworkProvider).put_TuneRequest(tuneRequest);
        Log.Log.WriteFile("dvb:Submit tunerequest done calling put_TuneRequest");
        if (hr != 0 && hr != 1)
        {
          Log.Log.WriteFile("dvb:SubmitTuneRequest  returns:0x{0:X}", hr);
          //remove subchannel.
          /*if (newSubChannel)
          {
          _mapSubChannels.Remove(subChannelId);
          }*/
          throw new TvException("Unable to tune to channel");
        }

Any ideas what the problem is?

Most likely you are using Vista TV pack. It is not currently supported, hopefully 1.1.0 will support it.

MS has changed the network provider in Windows 7 / Vista TV pack in such way that multiple tuning requests are failing.

Yes i am using tv pack. But does the "1" mean failure? Or does it mean something like: I tried but i did not need to do anything. The strange thing is i can ignore the "1" and everything seems to work fine.

Zero is success, all other values / return codes indicate a failure / error. Most likely the error can be ignored on that case as the tuning has been already done.

So, it the patch ( && hr != 1) helps on your system you need to keep using that until 1.1.0 is release

Is there a place to lookup such error codes? I have been searching but am not able to find it.

Same problem and i have vista tv pack too.

Help !

Same problem and i have vista tv pack too.

Currently Vista TV pack nor Windows 7 aren't supported. You can only wait until 1.1.0 release is out (or ask riksmith to provide modified binaries that has a workaround for the issue).

ok thanks for your response.
the next realease will support really that ?
