Playback Stutter via DLNA


#1

Setup:  DS210j and WDTV Live connected to a WLI-TX-AG300N ethernet converter

Firmware

DS210j: DSM 2.3-1141

WDTV Live: 1.02.19 (Beta)

Problem:

When I run higher bitrate Blu-Ray MKV files,  the playback begins to stutter.  Lower bitrate files have no problem. This is only when using the DS-210j as a media server.  Network shares does not show the same problem and playback is fine.

Other info:

The stutter appears to occur when the DS210j is sending data above ~5200Kb/s.  Below that no stutter occurs.  This occurred during one of the opening scenes of Inglorious **bleep**.  Playing The Hangover (via DLNA/media server) the bitrate remains below 4500 Kb/s and no stutter occurs.  

Playing Inglorious **bleep** via Network shares, same scenes, no stutter.

I’ve attached the resource monitoring chart for the network traffic.

Top Chart: The Hangover (DLNA)

Bottom Chart: Inglorious **bleep**

Minute 13 - 10: DLNA Stutter

Minute  9 - 5: DLNA playback good

Minute 4 - 0: Network Share playback good (same scenes as Minute 13 - 10)

I’ll upload the media info later today.

Any ideas?
