    Default DVR Window Duration more than 30 hours

    Hi!
    What I need to change in the settings, for example to record 48 hours?
    After I change the duration of the recording of more than 30 hours, entry is 5 seconds and disappears all the time.
    My dvrManifest_0033_00_00.txt in this period a piece of code:

    Hello,

    Here's an article the explains DVR recording options setup: https://www.wowza.com/forums/content...cordingOptions and related forum: https://www.wowza.com/forums/showthr...imits-for-nDVR

    Wowza nDVR limits the recording to 30 hours maximum.
