I also would like this to be active for more than 2 hours at a time. Maybe 12 hours at a time or something as described in other posts... 2/4/6/8/12/always ... something else. I've turned it on and left the house only to find that it was lost when I got home which was very disappointing and frustrating. I could have recorded the 2 programs, but didn't know I'd be gone so long.
Also, I ordinarily get very frustrated trying to get the 2 programs set up right. Down arrow twice when I'm on the first channel I want buffered. It then auto-tunes to 201... enter the number of the other channel I want buffered... no, that's wrong and I just lost all the buffering on the channel I started on. Then I start getting lost and quickly frustrated. I guess I just need to practice, but it should be more intuitive. The auto-tune to 201 needs to go, then I think it would fix my trouble. Leave me where I am so I can switch to the other channel right away.
