    Interesting article from What Satellite and Digital TV (July 2012, i.e. during DSO):

    http://www.dtg.org.uk/dtg/press_releases/dtg_whatsat_201207p20.pdf

    It seems auto-retuning is facilitated by the DTG but is optional. Or was then.

    And the DTG says:

    Network Change Notify descriptors (NCNd)
    Network change notify descriptors are used to signal significant platform changes. A start time and duration of the work is given, at the end of which receivers can offer the viewer the opportunity to re-tune and acquire the change. An associated message may be broadcast to inform the viewer of the work prior to the event.

    http://www.digitaluk.co.uk/industry/About_DTT/glossary_of_terms?result_76219_result_page=N

    From this it appears autotuning is still optional, as far as the DTG is concerned, and Humax could give users the option to disable it.

    Until auto tuning can be done without deleting users' recording schedules, surely everyone would want to disable it?

    Perhaps if Humax decided to provide an option to disable auto-tuning, the deletion of the timers would also be looked at.

    Speaking for myself, I don't find auto-tuning causes me problems. I don't at present own a Humax Freeview device, but my Panasonic DVD recorder auto-tunes if repeated invitations get no response. Timers are not deleted wholesale. Obviously there's always the potential for timers for an affected MUX to be wrecked by a retune, but I've never found that to be the case. All depends on individual recording habits of course.

    Humax YouView boxes autotune, without deleting all timers, or so I seem to recall. And, as mentioned, Humax's new Freeview Play boxes will need to Smart Retune, to pass the DTG testing. Perhaps Humax will now bring its DSO-era recorders in line, as it seems retunes can only become more frequent as spectrum is transferred to mobile.

    JamesB - 20 hours ago  » Humax YouView boxes autotune, without deleting all timers, or so I seem to recall.

    Yes the Youview boxes do retain all timers, or sort of.
    The Huwei ones are OK but the Humax ones can tune into a mix of transmitters. On my Humax Youview box I need to do the equivalent of a manual tune by connecting and disconnecting the RF lead at the appropriate point and then testing for symptoms of mixed transmitters. If I leave it to a normal retune it misses of almost equal strength I doubt that it could satisfactorily resolve all previous timers if it was left to its own devices on an auto-tune.
    If I always left it to alone to auto-tune there is no guarantee that the way it mixes transmitters will be the same on each auto-tune and therefor have resolvable timers. And also some new timers would fail regardless of a 2nd retune or not.

    Huwei Youview do it all fine.

    Sounds pretty poor.

    I wonder why.

    I'm not sure which is worse, the Humax Youview auto-tune or my typing in post #24. But hopefully you understand the jist of my post.

    I got the drift.

    I've seen complaints about the Humax YouView box tuning problems before, but hadn't realised it was that bad. I get a good signal from a single transmitter (Crystal Palace) so my YouView box had no choice but to tune itself nicely. So I never experienced the problems.

    Do you find the Huawei box ok in other ways? I've heard it's on the sluggish side.
