Dish Network Question?

Do you have Dish Network?

I could use a little help?

We have had dish for a number of year now, in fact our Dish Modem just gave up the ghost, so to speak. A truly long story, very long and boring, so the question is.
Do you have Dish HDTV?
This new box has people in a program speaking in a really low volume and when music comes on, it gets really loud! Also If we wish to hold a program and get back to it in a few minutes or so. If we pass through the commercials and a bit of the program and try to go back to the beginning of the program, it goes back to the beginning of the commercials?
The bottom line is, two techs say that it happens to everyone including them, is this so? Does this always happen to you?
