Hello,

I never used the iTunes Store, so I still don't know how to use it, really. If this has been asked a million times, I'm sorry. If there is quick link to read through all of this, I'm sorry too, I googled, but didn't find anything so quickly...

Questions...
If I download a song, what happens when my HD fails? Can I redownload it (free)? If I can't, what to do? Burn CDs/DVDs? If I buy a new computer, can I redownload everything (free)? I thought it would somehow 'register' the computer itself (which I thought is rather normal these days).
If I want to download a movie with my TV set, where does it save the movie? If the TV has no internal HD (as most TVs, I believe), does it simply use the DVR? Do I need a special USB HD for this? (And same questions for movie downloads and failing HDs here; I wouldn't want to rebuy everything.)
If I buy a movie to watch on my TV set, can I watch it on my Mac, too?
And lastly, if I buy in HD quality, and if I can watch it on a Mac, too, will it work? (as it would have to downscale resolutions, I believe, or is the SD version automatically available as well?)

I thought many people around here would use the iTunes Store, I don't know about so many other very large store for music/movies and I consider using it more, so I hoped I could get some advice...

(I hope this is the right forum, btw...)

Thanks!
Pete
