right so I got my HD PVR today, literally and hour and half ago, and i set it up, and it was picking up on my TV, great, but it wasn't showing me it on my laptop? so I had a look around on the internet, not much. I realised I might have to change my HD settings on my TV, so I did, (because I just put in the xbox cables with the HD bits for the PVR the default setting were 480i) so I changed them to 720i, worked fine, 1080i, worked fine, I changed it to 1080p and now nothing shows up on my TV? it works normally when I dont have the PVR connected. (i'm now back to 480i just to test) and it still won't come up when I am connected to my PVR? Help Please...
