Keep Until I Delete Bulk Change

[agent86]

I have over 1000 recordings that are keep until space needed because when I upgraded from windows 7 to Windows 8.1 I forgot to reset the default.

I just noticed automatic deletions occurring although I had a reasonable amount of space free.

I have changed the default setting to keep until I delete so new recordings are ok and I want to change all existing ones.

I moved the WTV files out of the recorded TV folder and put them back in hoping they would inherit the new setting but they did not.

Where is this "Keep until" meta data kept? In the WTV I couldn't find it in the properties, is it in some database on the media center.

I am happy to nuke the media center and rebuild it if that will help.

I have nearly 4000 recordings and going through them all is going to be very time consuming.

If there is some way of just ignoring the setting might be an option.

Traditionally I get notifications from ICETV.com.au that recordings will fail and in the scheduled recordings warnings will appear showing shows it does not think it can record due to space and I fix it then.
Any help greatly appreciated.
