I'm really bad at checking bills, I just pay them lol... Anyway today I looked at my DTV invoice and noticed they are charging me 6$/ receiver PLUS an additional $25 for "advanced receiver fee" what is this ? Is this because I have 2 DVR's ? I currently have 6 total receivers, 2 H24 and 4 H25's, If I swap one of the H25's for another HR24, will I be charged an additional "advanced receiver fee" ?
