One unfortunate side effect from S503 is when I attach an External Hard Drive and view its stored contents, the artwork images for random movies and shows has now been replaced by generic logos of the channels they were recorded on. (Ex: All episodes of Revolution now have the NBC HD logo). This doesn't make me happy since a lot of the shows I had stored have had their season/series finales or been cancelled. Therefore they're no longer airing to be recorded again and have the missing artwork overwritten. Also most of the movies were obtained from premium subscription channels during free previews, or they're simply not showing anymore. I can prove it was caused by S503 because the artwork was restored when viewed on my HWS with S502. Now that both have S503, the artwork is consistently missing for the same shows and movies on all EHDs.
