My Tivo crashed this afternoon. When it came back on, it would not allow me to watch Youtube or Netflix in standard def. I *HATE* high def. I'm trying to adjust to high def., since choice seems to be taken away from me. How do I get the on-screen clock display to work. (I used to: SELECT SELECT PLAY SELECT 9 SELECT. That doesn't seem to work anymore ... except in standard def.). Does this mean I cannot have an on-screen clock in high def.?? Thanks.
