Would appreciate some advice. Where do most of you go to check on upcoming premiers and specials for premium movie services such as HBO, Starz, Showtime, etc. .I know each service has its own online site but is there ONE source that is more convenient that you found? I'm not a big fan of the DirecTV Monthly Guide as most of the content is the ongoing daily programming which is of course duplicated on their tv scrolling guide. Any suggestions greatly appreciated. Thank you.
