Another youtube problem. Featured video in main channel

Anyone who uses Youtube is aware of the fact that you can put a featured video on your main channel page. Normally the still image you select in the Video Options will appear there in high quality. However, just randomly today, almost all my videos that appear in the featured video section of the main page are terrible quality now.
To see what I’m talking about:

The image on the right was the original video thumbnail for this video, before it was changed to what you see on the left.
Has anyone else noticed this with their own channels?
Also please go to my channel and confirm whether you see it in that quality as well. I’ve had like 6+ people tell me they see it in the same bad quality, but like 2 people said they see it in good quality still. Here is the channel:

Remember, it’s only the image you get before playing the video that I’m talking about. Not the actual video footage!

Sorry for the bump.
It looks like this is an official bug now on Youtube (Or so I think), after reading their forums I noticed their bug support section is filled with posts about this. Looks like I’m not the only one anymore.
