I have the 32PFL5507H/12 with latest firmware 30/7/2012. Connected over WiFi with a good 300N Gbit router. TV says connected at 68mbps. I can download at 40mbit/s with a laptop nearby the TV.

DLNA Streaming from a wired PC the TV can play 720p 6mbps mkv nicely. However 9 mbps 1080p movie stutters now and then ,14mbps and 24mbps movies choke badly.

The same files play perfectly from a USB stick! Is DLNA somehow limited to a low bitrate? This would be a great bummer, since then i could get no decent 1080p movie playback from a NAS i wan't to buy.
