viewing saved programs after adding aerial

Jack_M — Wed, 15 May 2024 14:40:44 GMT

Our BT TV box pro was originally set up without an aerial, so much of Freeview was unavailable. After adding aerial , it was necessary to reset(keep recordings), but now although the recordings are listed, they will not play, saying the channel has been removed, although it is still present. Any ideas how to get round this, I suspect a logical mismatch between the channel used to record and the current one in the guide.

@Jack_M

Switching modes (in either direction), deletes your recordings, even if you try and keep them. It requires a full factory reset.

You might need to reset again to clear any false positives.

Thanks stereohaven . I haven't been able to login as my username is invalid despite being allowed to register!

Would you recommend a reset(delete recordings) ?

The process of switching modes doesn't seem to be very good though does it

Thanks Jack

Sadly, yes. Full factory reset is required to change tuner mode.

It means setting up the box from scratch again.

You are mistaken a full factory reset is not necessary when switching modes. The factory reset (maintenance mode) will preserve recordings however recordings for the free to air channels when previously in IP mode will not be playable if you switch to aerial mode. IP subscription channel recordings will still be playable.

Well someone needs to add that to the BT Help page then I linked to in my original response.

@JackM2

As @zulu17 said, a full reset wasn't necessary when IP launched, but it's possible that's changed. Although duff info on the web site is at least as likely, if not more so given BT's appalling track record.

You could try switching back to IP mode while you watch the recordings, using your TV to watch any missing channels. Most modern TVs can also record to USB, but only a single channel.

It's a little more complicated than just "will or won't work". It depends on the channel, and the protection applied to it at the point of recording. e.g. HD channels recorded from DTT channels in aerial mode won't be watchable, but SD channels should.
Thus it's easier to just say that none of the recordings are watchable, so that expectations are reasonably set.
You should just be able to delete the unwatchable recordings though - I don't think you should need to fully reset again.

@DarrenDev

ITYM “HD channels recorded from IP channels” in this case, don’t you? Though knowing YouView, what you say about the reverse direction could well also be true…

But the logic of ‘protecting’ HD recordings at any level below that of the box ID/subscription status entirely escapes me, except maybe to ensure that you still can’t fast forward through the adverts on itv programmes recorded in IP mode?

I did, though, know that you could switch without a factory reset, as @zulu17 describes, and the Help instruction to always factory reset when making the switch was, due to such peculiarities, for the guidance of mavens and the obedience of non-techies 😛

My understanding is that:
* DTT SD recordings are stored as unencrypted video streams - the file could be copied and opened by any media player.
* DTT HD recordings are protected by a key local to the box, which changes after reset. This is to prevent them being copied.
* IP recordings are protected by a subscription key - as long as you still have a subscription to that content, it can continue to be played.

It's all moot anyway. Some recordings will work in some scenarios, but nothing is guaranteed and it's not a supported scenario. Best to just reset fully.
