When using the “Browse PC” feature (DLNA), the capability of your media server software determines the availability of certain playback functions such as 'Pause' and 'Fast-forward'. Your media server software application may not support fast-forward for certain file types, even though the same file can be fast-forwarded when played locally on your computer or mobile devices. Please upgrade your media server software application to the latest version. If this does not resolve the issue, please contact the vendor of your media server software.
