Hi again, Eric.
To do the quote thing, just highlight the text you want to quote and then hit the button that looks like this:
quote.gif (it's part of the reply/edit window that you type your posts in). You will see the tags that it creates in your edit window. If you want to attribute it to someone, you can type in the name like this: [quote=Otto]. Do that at the opening tag, but not the closing tag, and it will say that I wrote it. There's also a forum to post test messages if you want.
One thing that I forgot in my initial post was to say that I do believe you need a sub for HT. While most listeners can get away without using a sub for music (those that don't listen to organ music, etc.), most HT users do indeed require a sub for the full movie experience. Most speakers (even full-range floorstanders) aren't going to be able to supply the impact from the LFE channel. To really get that .1 channel, a sub is required.
In the end, a sub is good for both movies and music.
