Hello, this is my first post so I hope I have chosen the appropriate place to post this question. I have just bought a KDL40W5500, DAV-IS50 and Western Digital My Book World Edition NAS (White Light version) and am having a nightmare trying to get streaming working properly. My network has a BT Home Hub as the centre with a laptop(Vista) on the Wi-Fi(54MBPS) and an ethernet network on my power lines (100MBPS) with a desktop PC (Vista), The MyBook NAS and the TV connected. I can stream MP3s from both PCs to the TV using Windows Media Player (although they lose album art for some reason). I can also stream MP3s from the NAS to both PCs with no issues. The issue is streaming from the NAS to the TV. It does not even find any videos (mostly DIVX AVIs) and when it streams MP3s they play for between 9 and 52 seconds before they stop and the TV gives me a message saying "Playback not available". It then trys to play the next song in the album, folder, playlist etc... and the same thing happens. The timing appears random the same MP3 might play for 10 seconds or 40 before the error occurs. Another odd thing is that the artist tag is set to unkonw when playing the file, yet I can browse by artist and I know my tags are well populated because I spent ages doing it. The NAS runs Twonky 4.4.9. I have spoken to the place where I bought it and they will still take it back even if I have been fiddling with the software so if there is a better solution to Twonky and I can fudge my way through linux well enough to install it I will give it a go. I only have a few days to get moving though... So my questions are: 1) Is there anything I can do with my existing NAS to get things running? 2) Is there better software than Twonky or would an upgrade to V5 be a solution? 3) If I just give up and return the MyBook what NAS solutions do other people use? Ideally it needs to allow me to backup the PC Clients and serve data to my PCs as well as Audio and Video to the TV.
