Video Streaming Experience.

Motherboard: Intel D915PBL.
CPU: Intel Pentium Prescott 3.00 Ghz.
Memory: Total 2Gigabytes.
LAN - video: TP-Link TG-3269 1000mbps
LAN - internet: on board Intel 100mbps.
Media Switch: Netgear GS605 5 port switch
Interconnects: Cat 6 manufactured cables.
Hard drives:System drive - 1.5Tb Seagate
Movies: 2 x 2Tb Western Digital
Seagate 1Tb USB
Operating System: Windows 7

Audio: Yamaha RX-V457 amplifier using SPDIF audio
Video: Connected with standard HDMI cable

DLNA Devices: Sony BDP S-370 bluray player Australia (EU profile)
WDTV Live - WDXTV 1.03.49; 0.4.5.3
Samsung PS50C550 plasma TV
DLNA Software: Serviio v0.5

The video LAN, media switch and DLNA devices are connected independently of the internet LAN. There is no network sharing of files or communication activity between the two LAN networks.

Seviio will stream DVD VOB files to all three DLNA devices without stutter.

Serviio will stream some bluray media through the WDTV Live without stutter. The reference bluray used was Pirates of the Caribbean 3.

Serviio will not stream bluray media through the Sony bluray player or Samsung TV without stutter. The reference bluray used was Pirates of the Caribbean 3.

Observing the Windows 7 Task Manager, the maximum CPU use when streaming bluray video is about 40% with 50% maximum memory use. The TP-Link TG-3269 1000mbps maximum use is 2%. My conclusion is that the 100mbps ports on the Sony bluray player and Samsung TV are good enough to stream DVD video but not fast enough to stream bluray video. The WDTV Live will stream DVD video. Depending on the bluray disk title, the WDTV Live may stream some of the bluray disk content without stuttering.

I am not interested in transcoding video; therefore any transcoding options are not acceptable. Frankly; I think the only way to stream bluray video from a computer to a digital TV without stuttering is using a multiple display graphics card, NVIDIA GeForce GTS 250 or better and Windows Media Player with the bluray codec enabled or one of the commercial bluray software players. VLC Media Player and SMPlayer will not play bluray without stuttering.

to be brutaly honest your conclusion is crap.

Seviio will stream DVD VOB files to all three DLNA devices without stutter.- not all VOB files work but serviio has best support for them i have seen so far..

Serviio will stream some bluray media through the WDTV Live without stutter. The reference bluray used was Pirates of the Caribbean 3. - that would make sense as WDTV support alot of file formats natively, althogugh from the many post here on the forum WDTV is not perfect and has give alot of issues to some users

Serviio will not stream bluray media through the Sony bluray player or Samsung TV without stutter. The reference bluray used was Pirates of the Caribbean 3. - depends what format the file is in.. better support for blu ray is comming in next release

I am not interested in transcoding video; therefore any transcoding options are not acceptable. - Then most files will NOT play over DLNA as they would have to be natively supported by the renderer so uninstall serviio and plug ur pc directly to the TV

My conclution.

Remember serviio is free software and one of the best DLNA servers on the market at the current time, but sadly ZIP can not please everyone and the poster above is one of them.

@Cerberus,

You have just displayed your technical ignorance in LAN. I wired my home with LAN cables in every room so I could get rid of computer clutter. I did not purchase a high definition plasma tv so I could watch inferior video.

I am not going to waste my time discussing technical issues with you when there are numerous forums whose members conduct themselves in a professional manner to resolve networking issues. I consulted a friend who works in a computer department where there are over 2000 PC’s in use, specialised networking and competent professional support staff. They have a dedicated professional state of the art video editing centre using the latest technology. The centre is used to train students in professional video editing. I doubt that the average user would possess or have access to the technology or networking centre.

My friend did a mathematical calculation on the limitations of using a 100mbps LAN to stream video. There are also professional software tools to verify the LAN speed. The bottleneck is not in the DLNA server software regardless of whether it is freeware, open source or commercial. In fact the DLNA software inbuilt into Windows 7 exhibits identical problems as serviio streaming video through a 100mbps LAN. In view that Microsoft wrote Windows 7 to be used in a professional environment, I doubt Microsoft would display any software incompetence. The bottleneck is not in my computer. The computer idles waiting for the information to be inputted from the 100mbps LAN within the consumer device. The only way to stop video stuttering is for the manufacturers to install a memory buffer in the 100mbps LAN or change to a 1000mpbs LAN. Until then be happy watching transcoded video.

My conclusion is that the 100mbps ports on the Sony bluray player and Samsung TV are good enough to stream DVD video but not fast enough to stream bluray video.

I agree, DLNA is limited to 20Mbps for High profile H264/AVC video, with some Bluray Video, this maximum video bitrate can be reached, and cause TV or BDP to become unresponsive.
Video bitrate can be viewed with Bitrate Viewer.

erm hate to tell you but im a network operation engineer for a large business continuity company in the uk, so i think i have a very good knowlege of LAN stucture thanks
