I have a problem with my WD TV Live, hooked up to a video-projector via component cable.
The problem is, that the picture is way too dark for 720p and 1080i - the brightness however is correct for 576p (and maybe 480p - didn’t try).
I tried both - YUV and RGB - but that didn’t make any difference at all.
The dark picture can’t be fixed by turning up the brightness on the projector - the color information is lost (dark areas become completely black! In dark scenes often you can only see the lit half of the face)
I have the newest firmware installed, which fixed the “red eared” people issue (wrong color conversion for most HD content).
