When you say that MC can't see the .ts files, I asume you are using MC as a DLNA controller/player? Does it actually see and connect to the Twonky server, or does it connect and then just not display the files?
I meant that MC 15 could navigate to the Humax on the network, and navigate to the Video folder, but showed the folder as empty. I have now fixed that, (the *.ts file association was not set. I found it under Options, and set it). However, MC then didn't seem to list the *.ts files directly, but rather their *.tac files, which when selected, did not play anything. I then discovered that the list of movies on the Humax (found under Drives and Devices, My Computer, My Network Places, Video on Foxsat HDT Network Services) were, in fact, just links. If I navigated to Drives and Devices, My Computer, My Network Places, Entire Network, Microsoft Windows Network, Home, Foxsat-HDR, Video on Foxsat HDR Network Services (where the previous link was pointing to), then I DID get a listing of the movies, showing each one with its *.ts extension. BUT, selecting any movie and pressing PLAY, brought up an error window that said, "The media type of this file is not recognised". If I right-click on the movie, and select Locate, to bring it up in Windows Explorer, then right-click it and Open With, and select either VLC or xbmc, then they both play it fine.
DNLA is currently working on a WAN, if by a WAN you mean across the Internet. Twonky is on the Humax streaming DNLA-compliant video files, which can then be viewed using xbmc on a remote PC. When I give my friends in other countries the URL/Port (of my router) they access the streams, and can select which movie to play, no problem. (I can also navigate to the Video folder on the Humax, using any browser, from any location on the Internet, and download any of the files located there, and play them using VLC. But that is not what I want, I want to stream the videos).
My problem, is that I want to be able to experiment and test my streams across the internet myself, without having to call my friends, but cannot, as the only machine I have access to on the internet side of my router, is a commercial server that I lease, and xbmc will not install on it (I am in Germany, my server is a Leaseweb dedicated server, used to host my Virtual World, and the graphics for my websites, and is physically located in the Netherlands). xbmc needs a graphics card to work, and commercial servers typically do not have one, usually just an integrated graphics chip (my server uses the Intel 945). This is the reason I am looking at alternatives to xbmc, and why I need to know if MC will install and work OK on a machine running Windows Server 2008, and which only has an integrated graphics chip. But, as I mentioned above, I cannot get MC to play my recorded files when MC is installed on my main home PC on the same network as the Humax (my home PC is dual Core, 3Ghz, 32 bit, running Windows XP, and an Nvidea 8800GTS graphics card).
Any thoughts on why MC wont play these *.ts files (while VLC and xbmc can)?
And to answer the second part of your question, I do not need MC as a DNLA server, I am quite happy with Twonky performing that role, and anyway, if I used MC as the streaming server I would need to keep my PC permanently on while I am away from home, in addition to the Humax, which I see no reason to do. I am using (or am attempting to use) MC purely as a player.

Edit: I have now found that by downloading CCCP the *.ts files play OK. It is a pity that MC does not play these files 'out-of-the-box' and has to rely on an open-source codec pack. At the very least, for commercial software, I would have expected to find, under Supported Files, a note to say that not all *.ts formats are supported (how many varieties are there, and which flavor does MC claim to support?), and suggest the CCCP codec pack, with a link, and indeed similar notes for all file types that it is known that CCCP solves for MC.
