OK something really odd. Yesterday, when I played any videos, they all appeared normal. Today, however, it appears that the red channel has disappeared from only the video playback. I tried VLC, mplayer, movie player, etc. All the same. I all my still pictures, jpg, etc are all ok and the color is normal.

I recently (about 5 days ago) updated to 8.04 LTS on my Dell 530n. Other than the red channel being gone, the videos and sound play normally.

Since it worked yesterday, I can't help think that some kind of update might have been pushed out, but normally Synaptic asks whether you want to install the new download.

Any ideas???
