I just got the software update and found that my suggestion was implemented to fix a pet peeve I had with the Series4: Turning on the real time and elapsed time counters (select - play - select - 9 - select) resulted in a display in tiny print in the very center of the screen. I mentioned this glitch back in March to one of the CS supervisors who happens to sit on the software update committee and he said he would bring it up in their next session. The problem undoubtedly had to do with writing the appropriate code for the HD displays so that the type size and location would display properly in this format.
If my experience is typical, you still have to select the SD display format in order be able to enter the code to turn on the real time and elapsed time displays. But now, once you've turned them on, you can go back and reselect the HD display and VOILA! you've got a usable time display in the top right corner of your screen.
I preferred the old location at the bottom right. But I won't quibble. I'm just happy to have my temporal reminders back! Thank you, TiVo, for listening
