Comcast, seriously?

I'm having issues with my one TV. There are four main issues.

1. A lot of channels have no sound
2. Some channels have sound for the TV show, but not for the commercials (not sure if this is really a problem)
3. Some channels are in Spanish...like channels that aren't supposed to be in Spanish....like Family Guy on TBS is in Spanish
4. This is my favorite. Some channels have director cues in the sound. "He reads over the letter that was just handed to him and sighs deeply."

I'm not sure how cable boxes work, but who knew this was even possible?
