I have a 625 dish dvr. Last night it started acting up. It won't rewind, pause or record on live tv. I can watch programs we have recorded and also watch live tv. When I try to record the red light comes on the front and the red record light shows up on the screen when you hit cancel like it should, but the program doesn't show up in the record list. When I push rewind or pause it shows a red icon on the screen with a line through it. Has anyone else had a problem like this? Thanks Pat
