Changing channel with the remote "Channel" button is all of a sudden ridiculously slow since the update this morning. TiVo Premiere XL. I am referring to the actual changing of the channel NUMBER, say from 809 to 810, when pressing the "Channel Up" rocker button. I of course restarted the TiVo but the issue is not resolved. Has this been noticed by anyone else? I presume this is the update that everyone was referring to in the 11/28 beta thread?
