What tuner are you using? (e.g. is it network attached or a PCI card?) Here are instructions for PCI(e)/USB tuners.
You need two programs running in parallel (in a command line window), one for tuning the channel and the other for looking at the data stream.
Program A: mythfrontend watching LiveTV on the channel that doesn't get guide data (or dvbtune in monitoring mode with manually passed tuning parameters)
Program B: dvbsnoop -n 1 -nph 0x11 # for SDT - should always be the same
dvbsnoop -n 1 -nph 0x12 # for EIT - lots of different sections - e.g. one per 3 hour window
if you are not watching on the first DVB adapter, then you need to tell dvbsnoop by adding "-adapter x" to the command line, e.g. directly after dvbsnoop
Hi, thanks for your advice, I think I have collected the information requested.
The first time I ran it, I only got a small section of information:

I then ran it again a few minutes later, and got a lot more details, and it mentioned sbs so I hope it is right.
