I am not sure if it's a problem with Cox or my TiVo HD, but just last night my wife tried to record 2 programs. One was just a black screen and the other had no audio. The one with a black screen was a digital HD channel and the one with no audio was a standard analog channel. Also, we have Entourage set to record every week on HBOHD and there was audio for about the first minute then it cut out. Is this an issue with my cable provider?
