You asked a lot of questions, and are kind of all over the map. When you do that, I think that paragraphing your post is REQUIRED. Split the topics and/or individual questions into separate paragraphs.
This is not just for me, but for you as well. The odds of someone reading this, who indeed might be able to help you, will be tremendously improved.
It takes effort, and a decent short term memory to try and address your post.
Let's see if I can remember what the heck you asked (which DID take effort to even read):
I don't know about analog and DVI, but AFAIK, DVI is just fine for the foreseeable future, as long as only having video there is ok.
Regarding remote programming, it's something YOU have to do. (Not that you ever mentioned what your remote model was). If you think someone is going to sit here, step by step, in programming every button for you, you have another thing coming.
Like I ALREADY said, it appears you only have 5.1 (which is 6 channels; the .1 is the discrete channel for LFE).
Therefore, with lossless mch tracks (such as TrueHD, DTS-MA, mch PCM), you will be limited to 5.1, with no use of rear surrounds.
The other issue with mch analogs is that you are relegated to the bass mgmt capabilities of the BDP itself.
Yes, you will obtain the best video you can produce, while getting the above tracks, with the stated caveat.
If, for any reason, you like to switch the audio output choice (HDMI vs optical vs red/white analogs) from your bluray player, I would further recommend Panasonic. I don't know about how other brands work, but Sony has historically made it a pain as they didn't shotgun the output (at least that's the case with s350 and fat PS3), and you'd have to delve into the menu to choose, say, HDMI or optical. The Pana's, it's just fine.
Wow, I feel like I was all over the place, and actually typed the above paragraphs out of order, placing them in between. Let's see how it looks. . . before I reread it (edit: yep, I DEFINITELY edited it multiple times):
Once again, please make your posts much more intelligible. Thank you for considering our position.
