I read some posts in the thread trying to find an answer to my problems, but to no avail...
Last Christmas I bought a bdt220 as a present for my parents so they could use it both as a blu-ray player and to stream movies from their LAN. The setup of the network is the following: as a router they have an Asus modem/router N55U with 2 wireless networks set up. On the 5GHz there's just a desktop pc, while the 2.4GHz network is used for the bdt220 and a couple of smartphones. Videos are stored in a Buffalo Linkstation Live NAS which is connected to the router via ethernet cable. The router is set on DHCP but with manual lease of the IP addresses of both the NAS and the bdt220. The NAS is working perfectly and it's accessible from every device. DLNA streaming is enabled in the NAS settings.
However I'm having some serious issues: even though the bdt220 is connected to my wireless network with full signal, if I search for DLNA servers, I can find and connect to my NAS, browse the movie list but no one will play (I get an error message stating that the content is not supported). But if I choose the "network drive" option from the network menu, I can see all the movies stored in there and play them (mostly DivX and MKV files, some HD, most not). The thing is I get random freezes of the blu-ray player: it gets totally stuck and the only option is to power off and on again. The freezes are completely random, sometimes after 1 minute of playback, sometimes 1 hour or more. I'm not sure if the freezing happens even when playing from USB (though I played a couple of movies and had no problems), but that would defeat the whole purpose of my setup (wireless streaming) and made the purchase of the Buffalo NAS completely useless.
Modem/router, NAS and the bdt220 have all been upgraded to the latest firmware and the issue is still there.
Any suggestion? Is there anything I'm doing wrong or anything I could try?
