Description (last modified by )
Running 0.22-fixes. My dish is pointed at 28.2E and I can pick up all Freesat and other FTA channels at that location. However ITV HD isn't playing ball. I'm aware that 0.22-fixes should be capable of getting it, but it's not happening for me.
I've tried rescanning the relevant transponder, with it set to pick up "All" channels. It finds around 30 MHEG channels and claims to insert them into the database, but no sign of the fabled 10510.
I've attached a database dump, if that helps. I'll also paste some pertinent queries below. Please let me know if you need any more information. In the meantime, I'm going to try something like UPDATE channel SET mplexid=21 WHERE chanid = 101005; , as that looks like the missing link. I'll report results tonight when it's broadcasting.

Can't get this to work either.
Don't think 11426v is the correct frequency. I know that is where many threads on the net and even on the mythtv-users list say it is where it should be but there is nothing called '10510' on that transponder.
There is something on 11428h with that name but tuning to that one in Myth only gets a partial Lock (LMs)
This is the output of dvbscan for that transponder

Any of the dvb devs suggest ways to debug this further?

paulh, you sound like you know what you're doing, but just to verify - are you trying this during ITV HD broadcast hours? It's been suggested on IRC that when the channel's not broadcasting, it's impossible to pick it up (not sure how accurate that is).

You will still be able to scan or tune to ITV HD outside of their broacasting hours, although all you will see is the ITV HD logo. I'm using 0.22 and have no problem tuning to ITV HD on the following settings.
Service ID = 10510 Frequency = 11427000 Symbolrate = 27500000 FEC = 2/3 Polarity = H Modulation = QPSK RollOff? = 0.35

We know what the bug is.

10510 (0x290e) 0c: AC3 0x0d4a
Certainly looks like 10510 to me :)

danielk, as I remember it I first did a Full Scan (Tuned) which found all the FreeSat? transponders except the one ITV HD was on (that's probably a deliberate ploy by ITV/Freesat to attempt to hide the stuff on that transponder and isn't a bug). Having found the transport was missing from the list I manually added the transport and did a 'Scan of a single existing transport' which found ITV HD OK but when I later tried to view it I only got a partial lock (LMs).
After comparing my db entries with StuartM's it became obvious why it wasn't working for me the transportid and networkid was missing. The only was to fix it was to manually edit the DB and add the correct transportid and networkid to the dtv_multiplex table.
The original poster appears to be trying to tune into the wrong transponder 11426v when it should be 11428h.

Thanks, it appears this may simply be a feature that hasn't been implemented yet. I think it might be fairly easy to do, so I'm changing the ticket type to a task.

Per report by Stuart M, ITV HD has fixed their engineering and ITV HD is now scannable.
I couldn't attach my database (2.6M bzipped). Please drop me a line if you want it.
