Auto-unprotect - understanding the process

#1
Hi,

I have recently installed the custom firmware and one of the packages I have installed is Auto-unprotect. I have done a lot of reading on the forums etc about it before installing it and starting the process.

I started it last night using Method 2 (WebIF-mediated auto-decryption) and it appears to be working as I now have some recordings with the green Flag 'Dec' showing next to some recordings. I also have a queue of around 500 recordings to be decrypted in the 'Queued Tasks'.

My PVR prior to starting the task was at 99% full (yes I should delete some recordings as I will never watch them all).

What I do not understand about the process and I am looking to understand is why has a folder appeared in the folder '[Deleted Items]' called 'webif_autodecrypt' and recordings are appearing in there and using up the last of the memory I had free now leaving me with a 100% full PVR?

The recordings appearing there are still shown in the main list of recordings and it appears these are recordings that have been decrypted. But why are they appearing in the '[Deleted Items]' folder?

Could someone help explain please as I am worried I am about to loose recordings I want to keep if they are automatically deleted out of the [Deleted Items] folder, are they going to be deleted entirely from the PVR. Also is there a way in which I can suspend to decryption process without re-encrypting the programs that have already been decrypted. As it appears to be slowing the box down so my thinking was to only run the process over night when the box would not be used normally and allow normal use during the day. For example could I click on ....My Video > OPT+ > Recursive Auto-Decrypt and use that as a toggle to turn the process on and off.

Any help in understanding this process would be very much appreciated.

The "deleted items" entries are only safeguards in case something goes wrong and you need to recover the original file. It was considered prudent when all this was new, but years of experience say there is very little to worry about and you could just turn off the wastebasket (remove the undelete package). Nothing gets put in the wastebasket you would normally want to keep.

I don't know why you would think anything will be re-encrypted. Once decrypted - it's decrypted.

You can restrict queue processing to specific times of day, eg in the middle of the night when nothing else is going on. Toggling the auto-decrypt flag may not help when the entries have already been committed to the queue.

The slowing down you report is very likely due to how full your HDD is. I recommend a good 20GB headroom minimum, so either strip out some of the crap you will never get around to watching, or fit a 2TB drive.

There is now an option in the settings menu to prevent the originals from autodecrypt and autostrip going to the dustbin retaining the benefit of dustbin for protection against accidental deletion

Thank you both for the replies, very much appreciated.

It was just my lack of knowledge thinking it may happen. Thank you for clearing that point up.

So the items in the wastebasket, are these encrypted original files?

So the (basic understanding) process of decrypting is:

1. Create a back up of the original file to be decrypted in the wastebasket
2. Decrypt the original file
3. If all has gone well move on to the next file to be decrypted and delete the backup created in step 1 above

There is now an option in the settings menu to prevent the originals from autodecrypt and autostrip going to the dustbin retaining the benefit of dustbin for protection against accidental deletion
Am I correct that this setting is the one in: Settings > Auto-Processing Settings > Create backup files in dustbin for decrypt and shrink? > Toggle Yes/No

And to avoid back up's I would therefore change this to 'No' from the defaulted 'Yes'?

Am I correct that this setting is the one in: Settings > Auto-Processing Settings > Choose hours during which automatic processing runs > Enable during / Disable during

And to be able to run the process of decrypting the PVR needs to be out of standby.

Sorry about these basic questions but having read various threads and wiki's I am not clear about it and much appreciate your help and time.

No, a new file is created during decryption, then the original is deleted/moved and the new file renamed to match.

Yes

Yes. Are these things not clear from the wording? They are meant to be self-explanatory.

And to be able to run the process of decrypting the PVR needs to be out of standby.
Yes.

Thanks for answering those questions, much appreciated. I have turned off the backup setting and changed the processing hours to work when I know the box won't be in use and I have also gone through and done a quick clear out of some old recordings that have sat on the box for ages which won't be missed to free up some space and I now have 40GB of free space which will hopefully help with the speed of the box. I will try and clear a bit more out later when no one is looking at what i am deleting ;-)

Yes. Are these things not clear from the wording? They are meant to be self-explanatory.
Maybe I was looking in the wrong place but I didn't see any mention of these settings in the explanation about decrypting. And I couldn't find any explanation of the 'Auto-Processing Settings' if they are explained somewhere could you point me to them. The main place I have been reading about the various packages etc is: https://wiki.hummy.tv/wiki/Custom_Firmware_Package_Notes

Well, no - because mostly they're not needed, and anyway the facilities have expanded over a long period of time and may post-date the write-up. I'll add a note to Method 2.

And I couldn't find any explanation of the 'Auto-Processing Settings' if they are explained somewhere could you point me to them.
I meant the wording on the actual control panel - the settings do what they say on the tin.

It's also useful to go to the original package discussion: https://hummy.tv/forum/threads/index-of-package-primary-topics.8005/

I would say they are clear(er) when you know about them and have some understanding of what they are there for but tbh I didn't have a clue what they were for as I hadn't seen any mention of 'Auto-Processing' and hadn't put 2 and 2 together and realised they were linked to the decryption process. I still don't know what 'Auto-processing log level' / 'How many days should completed entries stay in the queue' are for and can't see any explanation to help.

There are a few others like The TVDB Integration Settings that I would say don't really say on the tin what they are for but I haven't spent time trying to find out if I am honest.

Yes, I have been using that page to learn but there was no link for a topic discussing auto-unprotect so I wasn't able to find anything via that. Maybe it has been missed off the page by accident?

The index entry is listed, but I couldn't find relevant discussion to link to. auto-unprotect and unencrypt were amongst the first few custom firmware packages at the beginning of time.
