Can anyone confirm whether the RC66 control can turn off a Samsung UN48H4005A tv. The RC65 which I have does not appear to, suggesting a non-exact match which does not work, but the RC66 has one that is says should work. Also, does the RC66 have more codes than the RC65 as some descriptions say it does, while others say they're the same. I'm trying to find one (remote with a code) that will turn TV and Directv on and off together for my 85 year old mother who requires the very simplest remote for use. Ten minutes with a multi-remote and she can have everything inoperative (three times this week, an hour drive away for me). I have a plan to make this easier, but it does require the joint on/off operation of the two (don't even suggest a Harmony, WAY too many buttons). Thanks.
