Bravia DLNA to Vaio

Fireblader — Mon, 22 Nov 2010 09:07:01 GMT

Hi,

I own a Bravia KDL-46EX711 since this weekend. I'm trying to connect this TV using DLNA to

my Vaio laptop. The laptop is running Vaio Media Plus.

When I update the server list on the Bravia, it doesn't find any media servers.

The network connection is fine on the Bravia, as I can stream video from i.e. YouTube.

Both the Vaio and Bravia are connected to the same router, so they are part of the same network.

Any ideas?

Have you tried using a different DLNA transcoder like Mezzmo ?

thanks

I tried both Vaio Media Plus and Windows Media Player 12.

Haven't tried Mezzmo. Will try this evening.

Mezzmo seems to be working well for other users also

Do feedback if it works.

Thanks

Hi,

Installed Mezzmo this evening, but this also does not work.

When I let the Bravia search for servers, it doesn't find any.

Also tried using an old WinXP PC running Windows Media Player 11, but this also does not work.

(On the Vaio WMP 12 is installed)

I tried this last option, as according to Sony support they only support WMP11 for DLNA streaming.

Blah Blah Blah... on the Sony site itself they mention Vaoi Media Plus.

I just love good support 😉

Getting a bit frustrated.

Have you tried temporarily turning your firewall off and checking that UPnP is enabled on your router. If 3 separate bits of software aren't working, then I think the problem lies somewhere else...

uPnp was indeed not enabled in my router.

Enabled it yesterday and then my Vaio was listed in the serverlist on my TV.

Unfortately I could not connect to the server.

When I looked at the server details on de Bravia, it said it was disconnected.

Today I have reset my router, but still I couldn't connect to the Vaio.

I then removed the Vaio in the serverlist on the TV and tried to update the server list again.

But now the Bravia doesn't find any servers anymore.

This is really giving me a headache. One of the reasons I bought this TV was its DLNA capabilities.

Can't figure out what is wrong.

Hmm - is there a firmware update for your router? Try maybe also installing mezzmo or twonky also.

Thanks

Yep. Checked the router firmware also. It's running the latest release (Lynksys BEFSR41).

Tried Mezzmo also. No change..

Are you running the latest firmware on the BRAVIA? Best to checkout the tab at the top of the page and download it manually onto USB thumb drive and update it manually just to make sure? Maybe try it via another PC or with a friends PC to see if you can get that to work.The issue is that there are so many unique variables, its very hard to know how your particular setup is arranged and thus what the blocks might be.

You have TV which supports it and software which supports it, but for some reason your network isn't allowing the two to connect up. Could always try another router, if your ISP shipped you a free one to use, maybe give that a go as well?

thanks

Had some 'fun' again yesterday evening (NOT).

My network setup is as follows:

The router is a Linksys BEFSR41, running the latest firmware, with DHCP enabled.

The Bravia EX711 is also running the latest firmware.

The 4 port switch is infact an old ADSL router that I use as a switch (DHCP disabled and nothing connected on its WAN port).

Yesterday I discovered that uPnp was also enable in the 4 port switch. After I disabled it, the network became unstable.

I decided to disconnect everything, turn off the 4-port switch, and reset the Linksys router.

Restarted the router and first connected my Vaio (-> IP 192.168.1.100 = first addres in DHCP range).

The connected the Bravia (-> IP 192.168.1.101).

The I enabled uPnp in the router. Immediatly the network became unstable (duplicate IP adress errors, the laptop constantly connecting/disconnecting).

Again did a reset of everything. Only connected the Vaio, enabled uPnp -> unstable network.

I discovered this was actually caused by Windows Live Messenger on my Vaio. After I killed this, the

network all of a sudden became stable again. Reason ?????

Again did a reset of everything. Connected the Vaio. Connected the Bravia.

Killed Live Messenger and enabled uPnp in the router.

Bravia could not see Vaoi.

The disabled uPnp again (so I could start messenger again).

All of a sudden the Bravia saw the Vaio and I was able to stream pictures.

Restarted the Vaio. Bravia can't connect to the Vaio anymore. GRRRRR

Anyway, I don't understand why uPnp should be enabled in the router at all. uPnp has to do with applications

dynamically opening/closing ports in a firewall. The network traffic between the bravia and vaoi

doesn't pass thru any firewall. The firewall is only to the ISP switch.

I have an IT background and work in an industrial IT environement. But this really puzzles me.

This is more gut instinct but I think the problem may lie in the router. Networks shouldn't become unstable if you switch on UPnP. I've been running a Linksys WAG160G I think until recently and just switched to a classic Netgear DG834 (modem that most of the ISP's use) in the office and I have a stack of BRAVIA Internet Video devices hanging off that as well as numerous smart phones etc and that works perfectly.

Have you tried running the network without the second router/switch in case that could be causing a problem.

I don't understand why you would be able to view phots but not movies or music. Sure you are aware already but you need to browse video via the video tab, music via music etc. Despite all folders being visible in all tabs, you can only see actual files under the relevant tab.

It is odd though indeed. I'd look at trying a totally different router if possible.?

thanks

I will investigate this evening whether the problem is caused by the second switch (although I doubt this can be the cause).

Also I will add a simple 8 port switch, from work, between the router and bravia/laptop.

That way there should be no traffic at all going over the Linksys router.

Next step will be to lend my neighbour's router. He uses a DLNA application over it (NAS media server).

Can you explain why you mention to enable uPnp in the router? Like I said, uPnp is a Firewall feature, and

there is no traffic at all going over a hardware firewall in this network setup.

I don't profess to be a network expert by any stretch - but my understanding of UPnP in the consumer environment has always been as a series of protocols which allow different branded network devices to discover one another and share content. Thus enabling UPnP on the router is basically then allowing this discovery process to take place.

http://en.wikipedia.org/wiki/Universal_Plug_and_Play

Indeed the list of UPnP AV media Servers on Wikipedia makes frequent mention to them supporting UPnP

Hello,

I did some more playing around this morning ;-).... and the conclusion is.... that there is something wrong

with the Linksys router.

I changed the netwerk setup to this this morning:

Linksys router ----- simple 8-port switch -------------- Bravia

----------- Vaio

And... tata.... it worked perfectly. Connecting/disconnecting the Vaoi, and Bravia always rediscovered the media server.

I reconfigered my old ADSL router that I use as a switch / wifi access point, to act as a router again (just enabled DHCP again)

ADSL router ------------------- Bravia

------------------ Vaio

Also worked perfectly.

In fact when I let the bravia discover the media server using the first setup.

Disconnect the Vaio and reconnect it to the Linksys router, it still works!

So there is something wrong with the uPnp discovery over the Linksys router.

Also, all this time I had uPnp disabled in all routers. Like a said, the uPnp setting in a router is just a firewall

feature. Which is not needed for DLNA. DLNA can only transmit over the same subnet, hence no routing, but only switching is needed.

Remember that a router is just a network switch with some added features (DHCP, Firewall, network routing between subnets).

Anyway thanks a lot for your support. This was alot more helpfull than the response I got from Sony support.

No the only problem I have is finding a router that supports DLNA/uPnp correctly.

On the DLNA website only one router is mentioned.

I suggest you to have a look on www.serviio.com

Could be install to Windows/Linux/Mac/NAS, and could remux/transcode on the fly a lot of media format to Sony compatible DLNA profile

Thanks for your response, but this was not a Media server problem.

I found that the cause is my Linksys router.

When I connect the Bravia and Vaio to a switch, so no netwerk traffic passes the router, it works

perfectly.
