Do Detailed HDTV Listings Exist?

nick_davison asks: "Having finally made the move to HDTV, I've been getting up to speed on the usual debates about HDTV (is 720 rows/frame better than 1080 served every other frame, 540 at a time? Is 1080i meaningless if all your signals are 720, and thus 1080 is just having to resample your image? Is 1080i and 720p meaningless if the digital signals bitrate is so low it's garbage anyway? etc). Trying to form my own opinions, I went looking for TV listings that would at least show the resolution of the signal (1080i or 720p) and, ideally, though I guess less likely, the bit rate. What I ended up with was, if I was lucky, TV listings that differentiated HD and non HD shows on HD channels but nothing more. Do such listings exist? Is this something the TV companies deliberately hide? Is there any way to even piece together this information?"
