we have reported an error with adaptive DVR streams. Single profile streams work fine from the same application, but when we try to load a SMIL file with the same streams, we get 404 errors on the chunk lists. This does not happen immediately after starting Wowza, but after some time and we cannot determine why it happens. Even when adaptive DVR stream give 404, the separate streams work fine in all players. We are using wowza streaming engine 4.6.0. Please help. ---
