Hi Guys,

I am having a wierd problem with nDVR recordings. When I play the nDVR using the smil file like this:

[http://XXX.XXX.XXX.XXX:80/SVcatchup/smil:9-226750.smil/playlist.m3u8?DVR](http://XXX.XXX.XXX.XXX:80/SVcatchup/smil:9-226750.smil/playlist.m3u8?DVR)

Wowza gives an Null Pointer error like below:

2014-12-10 16:03:42 CET comment server ERROR 500 - HTTPStreamerAdapterCupertinoStreamer.onPlaylist: java.lang.NullPointerException|at com.wowza.wms.dvr.impl.DvrStartDurationPlaylistRequestDelegate.a(DvrStartDurationPlaylistRequestDelegate.java:192)|at com.wowza.wms.dvr.impl.DvrStartDurationPlaylistRequestDelegate.a(DvrStartDurationPlaylistRequestDelegate.java:180)|at com.wowza.wms.dvr.impl.DvrStartDurationPlaylistRequestDelegate.a(DvrStartDurationPlaylistRequestDelegate.java:151)|at com.wowza.wms.dvr.impl.DvrStartDurationPlaylistRequestDelegate.getDvrPlaylistRequest(DvrStartDurationPlaylistRequestDelegate.java:95)|at com.wowza.wms.dvr.DvrPlayerAdapterBase.getDvrPlaylistRequest(DvrPlayerAdapterBase.java:425)|

The smil file contains the following:

But if I try to play each of the stream in the smil file manually, it plays alright. Like for example if I do [http://XXX.XXX.XXX.XXX:80/SVcatchup/mp4:9-226750\_720p/playlist.m3u8?DVR](http://XXX.XXX.XXX.XXX:80/SVcatchup/mp4:9-226750_720p/playlist.m3u8?DVR) it plays without a problem.

Can someone explain where this error might be coming from?

Regards,
