Hi,
We have some test content originating from an Envivio encoder which we push to a live publishing point on our IIS server. We have the Media Services Smooth Streaming settings configured to archive the content at 1 minute intervals with an unlimited DVR window - here is the resultant isml file...
<?xml version="1.0" encoding="utf-8"?>
<smil xmlns="http://www.w3.org/2001/SMIL20/Language">

</head>

</smil>
The issue is that DVR seeking (fwd,rwd..etc) is broken on all but the first archived segment. We are testing this using a Silverlight based client and the behaviour of the player is to jump back to the start of the buffered stream when seeking is attempted. Our initial thoughts are that it is somehow getting confused as to the starting point of the stream - it is noticeble also, that the progress bar when playing back a 'broken' segment is always set at 'full' rather than progressing as normal..
As mentioned seeking works as expected for the first segment in the archive.
Here is a link to a sample of the archived content -

We are running IIS 7.5 with Media Services extension 4.1
Thanks,
Karl.
