Ok, so I have been very patient with my Apple TV over the last nine months. Its connected to the Vodafone VDSL modem by ethernet cable, then HDMI cable straight into the Samsung Series 5 48" LED TV. I use Unblock US.
It usually takes a minimum of three tries or a reset (not restart) to get a Netflix programme streaming, normally all I get is an onscreen message saying "An error occurred loading this content, please try again later". The programme will stream for about 10 minutes before I get a black screen and the same error message. On restarting the programme it will run for another 10 minutes before crashing again, and so on...
However when I plug in my Sony Vaio laptop and stream from there via HDMI it works first time every time.
I'm curious as to why I can stream from one but not the other (the one designed as a video streaming device).
BTW, I'm a self-taught user of technology, (not an IT guy) but someone who deals with filming, editing and uploading HD video content to clients around the world.
