Hi All, I've just bought a WD TV streamer. When streaming movies from my NAS drive, I find that 1080p mkv files are forever stopping and starting during playback. I get the orange spinning arrow thing (i.e. loading or buffering) and it lasts a few seconds each time. It was fine with a 720p mkv file. I managed to watch that from begining to end withoug a single hiccup. But 1080p files are unwatchable. It's all connected via CAT5e cable. Assuming this is a limitation on my network but can anyone tell me what checks/tests I need to do to verify this please? Otherwise the WD TV will be going back. Thanks, shr.
