Sometime I randomly have the server 404 is ask for a m3u8?DVR. At the same time the server responds correctly to manifest.f4m?DVR for the exact same stream/smil.
I run my ten identical streams and this might happen on just one, the process of stream creation is identical across each.
Does this occur more than once in the lifetime of the stream or just the once at some random time? If this is something that appears repeatable then please do raise a support ticket with us via the process outlined here. Please also include any steps taken to reproduce it.
