I just got the NAS and connected it to my local network at home with no problem. I setup the media server on the NAS and my TV find it with no problem. I put some picture, music and videos on it. Only to find out that the picture and music works with no problem. But when i try to watch a video i get unsupported file format. When i put the video on a USB Stick and connect it directly to the TV it works like a charm. The video are avi fils. I have the latest Firmware on both. Is this a problem with the TV or the NAS? And most of all how do I fix this?
Samsung TV: LE40C655L1WXXE
Seagate NAS: ST310005MND10G-RK

First, I think it would be helpful to clarify some things. These are things that I have found out through hours of research and experimentation. They are also fundamental to the success or failure of a network of DLNA devices and really should be made much more apparent to consumers of DLNA products. Until DLNA implementations evolve into more robust and complete devices that "just work", I believe frustration and disappointment will remain widespread.
DLNA certification is not an all or nothing guarantee. Just because both the NAS 110 and your Samsung TV have the DLNA logo doesn't mean that everything your TV is technically capable of playing will play through the DLNA service. If only it were that easy. DLNA Certified products cover a wide range of capabilites and so, there are twelve different DLNA device classes in three categories. "The DLNA Certified logo tells you that the product you’re looking at meets DLNA certification testing requirements. That means it has proven it can connect with other DLNA Certified devices." (quoted from dlna.org) So the only guarantee provided by the DLNA logos are that your TV and NAS 110 can say hi to each other, not that they are able to play all manner of media that might otherwise be possible. Essentially the NAS 110 is a basic network server that runs DLNA media server software in order to stream media to DLNA clients, or renderers, such as your Samsung TV. The capabilites of the devices and the DLNA media server software itself are often quite different. All parts of the chain must support a particualr file or format and it must be implemented through the DLNA model in order for it to work.
An explanation of the DLNA media format model and the specific subset of formats that DLNA devices might support can be found here. DLNA certification only requires at least one format from those listed be verified to work. Thus, the DLNA logo on the box is potentially misleading. Basic details about a product's DLNA certification, including which formats were tested, are available in a searchable database. According to dlna.org, the BlackArmor NAS 110 1TB (ST310005MNA10G-RK) has only officially been certified for MPEG and WMV as far as video playback is concerned. However, the NAS 110 is actually able to play more media types but it's essentially trial and error to figure out which additional file types/codecs work. The latest firmware update (1000.1081) added a much improved media server, although introducing new issues like not displaying file extensions! I have found that DivX/XviD, H.264, MPEG2, MPEG4(ASP), and WMV9 video formats all play for the most part. As for audio, MP3, MPEG-1/2, AC3, AAC are also generally supported by the NAS 110. Keep in mind there are specific variations within even these types of codecs that may not play.
"Media Service Upgrades
WiDMS 2.0 Media server upgrade, more robust than ever
Media Files can now play from any folder
Eliminated Drag and Sort
Added new media file type to the supported list (*.m4b, *.rmvb, *.rm,
*.m4v, *.divx, *.xvid, *.mkv, *.mts, *.flv using open source “ffmpeg”
The second point of clarification is that an AVI file is just a container that holds audio and video steams. Each of those streams are encoded with a particualr codec. The codec is what ultimately determines whether a file is compatible with your devices or not. This table gives a concise overview of all the various media file container types and which particular codecs they are capable of holding. As you can see, the AVI file format is very general and can actually contain many different types of streams. So saying the videos are AVI files doesn't really give any specific information about what type of audio and video streams they contain and therefore if they should be compatible. I use VLC to determe the actual codec information of most files, it can be found under the "Tools" menu. You will need to verify which codecs were used to created your AVI files and beyond that you may even have to consider the resolution, framerate, bit rate, and various other encoding options that may or may not be supported.
By now, one might think this is too complicated and frustrating...and I would say for the average consumer, it most definitely is. This is where the DLNA guidelines are working to reduce the number of variables involved to make the challenge of interconnecting devices manageable. "Digital Living Network Alliance (DLNA) is helping put an end to that frustration. A collaboration of the world’s leading consumer electronics, PC and mobile companies, DLNA has created design guidelines for a new generation of DLNA Certified products that can work together — no matter the brand." (again, quoted from dlna.org) Unfortunately, guidelines still allow for plenty of room for incompatibility...at least in my experience. FYI my home network of devices consists of two LG "Netcast" TV's, several computers (four XP, one Vista, two Win7), NAS 110 1TB as a shared network drive and media server, Nero MediaHome Essentials DLNA server software running on the Vista PC, and even my Samsung Vibrant which has the AllShare DLNA app. But hey, they're all DLNA certified...right??

@Mediumpace: Thank you for supplying such a concise answer - if only Seagate "support" were as useful! I have spoken to several very technically minded people who have setup (or tried to setup) media streaming at home, and all have come up against enormous frustration because almost nothing ever works properly, no matter which products they have bought.
The whole industry is a complete mess, with the DLNA organisation doing little (it seems) to help the situation for customers - while allowing big corporations to slap a DLNA logo on their products which is completely worthless.
I just wonder how many millions of people around the world have to check each week to see if their duff 'dlna certified' product has had a firmware upgrade that might actually make it work?
(Note: I gave up with my useless NAS110, extracted the hard disk, and installed it in a nice Synology DS109. What a relief! Now I have a useful product rather than a pretty little paperweight!).

you are right but there are some missing informations that I do not founding or understanding.
Actually I have installed NAS110 without problems, and I can read files from any PC.
The most problem is abut TV Samsung that show the files but have not access to it.
Infact the message is "wrong file format".
I think that it is only a permission that the television do not have.
I investigate a lot about internet but I have not finding any solution.
Please let me know if there is possibility to solve or I must to by another NAS

Well, the Seagate BlackArmor works really well as an NFS server over LAN (see this HowTo for setting it up: How to mount NFS server with autofs - openSUSE Forums)
BUT most of the features are either broken or simply don't work as advertised - totally misleading information:
- Media streaming - doesn't work, most formats unsupported
- Global Access - doesn't work or broken
- FTP access - darn slow
- HTTP access - only server configuration (must be able to set up web server as well)
- Back up - doesn't work or broken
- NFS server - the only feature that works and surprisingly really well
- Manual - absolute rubbish!
- No GPL sources available (must be violation of the GPL license)
- Seagate Tech Support - what is it?
So, if you want just a NAS with CIFS/FTP/NFS - go for it, if you want more from it - stay away, find something else, don't waste your money and time
