Max. speed

What is the maximum speed transmitting files between PC and TV LIVE through the LAN? Is it 50Mbps only or is it possible in some way increase it?

That’s a loaded question.  :)   It is capable of transferring via raw SAMBA close to 90 Megabits per second.   But it cannot play STREAMS that fast; they’re limited at closer to 50 before they start breaking up.  

Well, got one for X-mas and very happy with it. :smiley:

Did some testing with the famous Birds scene and it seems my player starts having trouble with > 34 Mbit/sec.

(Streaming from SAMBA share over ethernet.)

I can play the 42 Mbit/sec Birds Scene fine if it’s attached to local USB port.

Looks like streaming over Ethernet seems to have some performance issues.

I hope WD will support NFS in the future.

Because this protocol uses less overhead  I expect it will perform much better.

(My NAS supports NFS.)

More people tested with 1080p Test MKV examples (from Birds scene Earth movie)?

Please tell us your results! :smiley:

-Edit- New firmware same result with SMB streaming.

34 Mbit/sec = stuttering.

I can confirm that

I played it from my computer to a WDTV Live via network shares without any stuttering. I am connected via AV power plugs so it might be that your network is somehow slowing things down.

After an entire day of testing i found the problem.

My d-link gigabit switch (DGS-1005D) is creating the problem.

When i ping the wd player, it dropped a lot of packets while watching a movie.

I don’t have packetloss on any other devices on my network and also not on the WD when i’m in the players menu.

Only when the movie is playing it drops packets.

This is the reason why i have problems with high bitrate movies.

I temporary replaced the switch with my old US robotics 100Mbit switch.

Now everything works fine.

Wd TV live seems to be incompatible with my DGS-1005D switch.

The question is now, does this only happen with my switch or are there other gigabit switches with the same problem? And can it be fix with a software update for de WD TV live player?

I also found a related topic on another forum

Gorson, thats interesting. Does that switch have interface statistics? How did you discover this? Is it dropping receive or transmit packets? Might it be a duplex mismatch issue?

I just pinged from my computer that is connected to the same switch while the WD player is streaming from my NAS (readynas duo). I can also replicate the same problem while streaming directly from my computer (windows 7)

There is no reason for the WD to stop responding to my pings.

If it can’t handle my ping, then there will also be a problem in the communication between NAS and player.

With a 100Mbit swich, not a single packets gets dropped. Even the time in milliseconds stay <1ms

I also played with higher and lower MTU settings (on computer and nas) but that appears to create more problems.

Every UTP cable has also been replaced.

100Mbit switch:

Now the part that i don’t understand…

When i connect the 100Mbit switch between the gigabit switch and the player, the problem stays…

Even when the WD is not directly on contact with the gigabit switch.

It’s appears that the gigabit switch ‘detects’ the movie stream and is **bleep**ing with the packets.

This can be caused by wrong MTU settings, but there is no way i can change them on the WD player.

I just swapped my DGS-1005D for another identical DGS-1005D that i used for my seperate digital television network.

The problem still occurs, so it’s not just a randomly malfunctioning switch.

Tomorrow i will buy a new gigabit switch from another brand.

I have don’t all the tests again with a gigabit Cisco switch… no more packetloss… no more stuttering in very high bitrate movies.

Problem solved.

Which Cisco did you get, so people searching find good info?

I use the NetGear GS-108T by the way, and they work great.   They’re managed, too.  :)

Cisco Small Business SR2016  16-port.

I loaned one for testing from a colleague (working for an ISP has it’s benefits).

Now i know that buying a new one will solve my problem.

But just to be clear, Bird 42 is still my absolute max i can stream.

I’m shure that performance can be inceased with just a firmware update.

What means - connected via AV power  plugs?
