I've just started looking at my nebula DVB using Graphedit. I have managed to get it working!!! However, I have no idea how to configure the tuning paramteres to choose a channel at will. So far, I have stumbled across channel 7 by chance.

Any pointers?

In the tuning space prop page, enter the freq eg. "177500" for Ch7, and then hit the submit button before playing the graph. If you want to change channels then enter the new frequency and and also enter "-1" for the ONID, SID & TSID before submitting to cause the NP to retune. If you know the SID values for a network then you can also enter these and change to the sub program.

Thanks bear, that works! Only one being tricky is SBS (Sydney)...

Some frequencies have a +125kHz offset, eg "585500" ch 36 digital can be "585625" so try increasing the frequency on the problem channel.

No luck there, unfortunately. It seems that for some of the channels, -1 will do for ONID, TSID, SID - and then it auto-detects the right values. But for some of the channels, it seems to need to know what these numbers are in advance? Or perhaps I need to change one of the other settings?

Try rebuilding the graph for each new channel to see if it will auto detect the values.

AFAIK all the other settings should be "NOT_SET" or "METHOD_NOT_SET" except for symbol rate which should remain as "-1"

When you submit "-1" for the other values it should force the TIF to reparse the data using the new freq.

You should only need to put in the frequency and bandwidth 7 MHz
