通过查看IIS Media Service的Schema， 可以检查用代码对Channel的操作是否正确。
这里要对DVR的设置要注意：

          <ClientConnections enabled="true">
            <WindowLength>PT2M0S</WindowLength>
            <ClientManifestVersion>2.2</ClientManifestVersion>
          </ClientConnections>

1. ClientManifestVersion:

    不同版本的IIS Media Service版中，该Value是不一样的，4.1版本中，ClientManifestVersion=2.0； 4.5版本中，ClientManifestVersion=2.2;

2. WindowLength

    时间值参考http://www.w3schools.com/schema/schema_dtypes_date.asp
