Bad picture quality when playing sample media

I copied the sample movies supplied on the WD CD with my WD TV LIve player to the attached harddisk to see the HD quality. When watching the samples, there was a lot of purple and green banding and an overall bad image quality. The WD TV Live is connected via HDMI to my TV. Is this a bug in the WD TV Live?

Welcome to the forums.

How does the menu look?  If you look at any sample still images, how do they appear?

You mght also try going to the HDMI setup (in audio/video settings) and change it from “auto” (the default) to whatever resolution your HDTV supports (like 1080p) and see if that changes anything.
