I did some more research and answered most of my questions. LOL. I'll reply here just in case anyone else finds this thread in a search like I did.
I found the only difference between the HW-E450 and HW-F450 is that the F has the wireless connection to the TV. So I read the whole 22 page E450 forum
I found that Samsung TV's do not have a CEC on function, only an OFF. That's why it will turn off but not on.
I didn't know what ARC was, that's Audio Return Channel so yes HDMI does work in reverse from the TV to the Sound Bar.
I found that once hooked up with HDMI CEC on a Samsung TV the volume can control the Sound Bar and has an on screen display.
I read that the F450 Soundshare mode has an Auto on function but won't work till new TV's that will be released in 2013.
So it's really the TV's fault that it won't turn on because the TV has to send the signal or an STB and I found both my current DirecTV HD DVR and Future TiVo Premiere XL4 do not have HDMI CEC so that won't be any help.
I'm really hoping that older model TV's can be upgraded with a firmware to add CEC On or the new SoundShare On functions if its just a software thing and not a hardware thing. Maybe if we all email Samsung and ask them to add CEC On like other TV's have.
So after finding all this out the only two things that bug me a little about the HW-F450 now is that it sucks up dust like a vacuum and gets really dusty fast and it does not remember the dim mode, once the unit is powered off and back on its bright again.
I did think of one solution to my problem, when I get the new TiVo it comes with the TiVo Glow Remote and it's a learning remote so I can program the mute button to power my Sound Bar. I used to use the Mute button from my old TIvo Glow remote from my Series 3 HD TiVo as a sleep timer function. I never watch live TV, its always something from my DVR so I don't need a mute when I can just pause it.
Thanks, if anyone has anything to add please let me know
