OK - A recent update to the WebIF has solved the problem:
How To Avoid Flattening a Wanted Series Folder
The Problem
With
flatten running, a series recording creates a folder and makes the recording in the folder (as usual), but soon afterwards
flatten moves the recording into My Video and deletes the folder, making it a very small time window in which to go in with the WebIF and mark the folder "not for flattening". One can create a series folder oneself, mark it "not for flattening", and move the recording into it, but unless the folder name is precisely correct the next recording in the series will be made to another newly-created folder and then flattened.
Disabling (by uninstalling)
flatten temporarily is not ideal, because with it disabled the WebIF no longer offers flatten-related options (ie the OPT+ option to mark a folder "not for flattening", and display of the flatten/noflatten icon). One
can disable
flatten while the recording is made, then come back later and reinstall
flatten, then quickly mark the series recording folder "not for flattening" before
flatten does its job - but it's all a bit of a fuss. Alternatively one can FTP (or network-share) a
.noflatten file into the folder before reinstalling
flatten, but this is doing a job manually which should be what the WebIF is for, and again one still has the fuss of uninstalling/reinstalling
flatten.
It is possible to stop
flatten deleting a folder by dumping a file (any file that is not a .ts) into it -
flatten only moves a file set associated with a .ts file (ie the actual recording) and then will not delete a non-empty folder. This means that broken AR series recordings create folders which do not get flattened. However, unless you uninstall
flatten temporarily the window of opportunity is again brief (ie while the recording is being made and until it gets attention).
The Solution
- Create your series recording schedule as usual.
- Create a folder you wish the recordings to be filed in (any name you like, but immediately below My Video - I don't think this works with deep nesting).
- Mark the folder "not for flattening" - this can be done by starting the folder name with "[", creating an empty file .noflatten within the folder using FTP or by networked access, or using the OPT+ options in the WebIF media browser (preferred).
- Using the WebIF, navigate to the item in the recording schedule. Click the "more" icon and select "Change Folder". Enter the name of the created folder. This will cause the series recordings to be stored in your folder rather than an auto-created series folder.
- The Humax will require a restart before the detail change takes effect. When I tried leaving it to a normal startup (actually when the recording was due to start) the folder change didn't take, so accept the offer to reboot straight away. Thereafter the WebIF listing of the recording schedule shows the recording will be made to your nominated folder (and it does).
