DVR listing navigation problems

I was a 20 year user of DIrecTV satellite service, and recently switched to Stream. I have found that many of the convenient navigation features for the DVR listings. Example- you finish watching a recording and want to return to the DVR list for another older recording, but the Stream service automatically takes you back to the beginning of the DVR recording list, so you now have to scroll down one line at a time. THis is also a problem. DirecTV satellite service allowed you to use the page down feature which Stream does not do. Several other features also do not work. Am I missing some tips and tricks?
