Wireless connected videos stutter

WD Legacy Products WD TV Live Streaming
1

My setup:

Windows 7 64 bit running Mezzio as media server

NetGear N600 Wireless Dual Band Gigabit Router WNDR3700v2

WDTV HD Live Media Player w/ NetGear WN111v2 Wireless dongle

jperf network performance over 120 sec ping consistently shows 35000+Kbps throughput to HDTV Live.

This file plays fine:

MKV - video stream: 3961 Kbps, 1280x720 (16:9), at 23.976 fps, AVC (High@L3.1)(2 Ref Frames)

           audio stream: 384 Kbps, 48.0 KHz, 16 bits, 6 channels, AC-3

           subtitles: None

This file stutters after a couple of minutes:

MKV - video stream: 4930 Kbps, 1280x720 (16:9), @ 23.976 fps, AVC(High@L3.1)(CABC / 5 Ref Frames)

           audio stream: 1509 Kbps, 48.0 KHz, 24 bits, 6 channels, DTS

           subtitles: English, UTF-8

Can anyone explain why the 1st video plays fine while the second is unwatchable?  I don’t understand everything there, such as CABC??? or how DTS audio might significantly impact playability.

The second file is not supported due to the Video coding (CABAC: is only supported in Main and higher profiles and requires a large amount of processing to decode compared to similar algorithms)

So even the file shows as an MKV file, is also important to know what is the video encoding that is on the file.

This is the list of the codec that are supported for the .MKV extension

Video:
AVC
DivX (3/4/5/6)
MPEG1/2/4
Xvid
Audio:
AAC
AC3
MPEG Audio
PCM
DTS
FLAC

Please post the full TEXT output of MEDIAINFO for such a file.

The WD supports CABAC just fine as far as I can tell…

just look at the bitrate

that’s a huge difference as well,

3961 + 384 = 4325 kbps

vs

4930 + 1509 = 6439 kbps

maybe youre network doesn’t support that throughput, have you tried the same file from a local drive
