I wasn't planning on starting a new thread with my first post, but anyways....I was watching TV this morning and all of a sudden the show switched over to a condo infomercial-type thing. I can't change the channel. I can't even get a guide. I reset my cable box and when I turned it back on, the same infomercial was still playing. What is going on?! Anyone else have these issues all of a sudden?
