I am experiencing excatly the same problems but with 802.11n. I am using Linksys equipment WRT610 and WET610 - wireless bridge. I haven’t treid it yet with a cable but it seems, the WiFi connection is the problem.
Does anybody knows something about buffering in the WD TV Live? Or is the Ethernet socket a 1 Gb/s or only 100 Mb/s?
Thank you and wish you all nice holidays.
