The S3 never had a serious problem with macroblocking, at least not to the extent that people were jumping up and down and getting mad like they are with the HD. I had some small problem with macroblocking with my S3, it didn't seem to be anywhere near as bad as the HD has it, and it seems to have cleared up. It may have been TiVo who fixed it, or it may have been my cable signal got better. I don't know which. How slow is slow menus? I think they're a little sluggish at time, but all my TiVos seem to have been like that.
