Was watching an episode on side 2B of the ER Season Two set, and had screen freezes and blatant pixelization at numerous parts. Checked other episodes on that side, and same problem. I remember I had problems with my original purchase of ER Season One, and posted here. Many said it was because of the process and type of discs used - double-sided something or others. Apparently they are very prone to error. Anyone else experience problems with this set?
