I see. The "ah crap" kinda threw me off.
That's right. The mini does not have HDMI. It does have DVI, which is basically HDMI without the audio.
1. aTV does not work with ripped DVDs out of the box. I think there are hacks that can do it, though.
2. aTV can do this.
3. aTV can do this.
Yes. The mini can do all of this. The disadvantage of a mini vs. aTV is the interface. Front Row is not quite as slick as aTV's interface. Also, because the mini is more functional, now you will need a keyboard/mouse for the living room. Although a Wii remote and Remote Buddy look pretty cool.
For the most part, yes. The deal is whether you have the proper Quicktime codecs. The basic rule of thumb is if Quicktime Player can play the file, Front Row can.
Depends on your TV. If you're using DVI, HDMI, or VGA, you'll need audio inputs on the TV for it. Like on my TV, I have 2 HDMI ports. One of them has L/R RCA audio inputs for it. The other doesn't.
Probably, but I'm guessing that the Belkin cable is priced extremely high. Do yourself a favor and check out monoprice.com to compare prices. I bought a 10 foot HDMI/DVI cable for $18. (if the belkin is a better deal, then get that)
