Yep, I put up a list of MPEG-2 patents and MPEG-1 Audio Layer 3 patents.  But I didn't put up a list of MPEG-1 video patents or MPEG-1 Audio Layers 1 and 2 patents because I have not found anyone saying that they have them.  

So basically, I haven't found a list of MPEG-1 patents (other than MP3 patents), and no one on this list has managed to name any.
