Can I shoot 60i for worldwide HD and SD video release?

My camera shoots 1080/60i, not 50i.
I need to shoot HD video that will be used in different countries. Can I shoot in 60i and then have it converted to 50i? Do I need to have a DVD or a BluRay 60i release converted at all? I understand than in Asia DVD players take 60i and so do LCD/plazma TV's. I know that in Europe practically all VHS recorders played NTSC 4.3, not 3.58. I believe that it was to allow playing US produced tapes on PAL TV's w/o conversion to PAL. So is it OK to shoot 1080/60i and do not convert the speed for worldwide release, maybe just change something else, not the base speed of 30 fps? I don't know what would have to be changed. Could someone enlighten me? Also new DSLR cameras that shoot video, usually shoot 30p, which is great for Internet and probably can be played on DVD / BluRay worldwide. Am I right? I also understand that 60i is good because you can convert to 60p for 720/60p, plus you can create 120i or 60p (please correct me; I don't know, which one is right) for 2x slow motion or just use the 60p for slow motion on 30p. Do you know if the camera can also do fast motion, or does it have to be done in post?
Can 60i be used on digital projectors in theters with digital projection? I know that both Christie and Sony projectors are used in theaters. Does anyone know which formats they accept?
Which formats do festivals accept?
I'd really appreciate a reply. I asked in another forum and no one answered me.

For questions about what formats networks or festivals accept, ask them. Delivery specs vary widely and change from time to time, so go to the source. If you need to deliver in 50i you can convert your 60i program in various ways using software or hardware. As for DSLRs, do some research on specific specs. Most of them produce files that require some kind of conversion before they can be edited in a NLE. Of course, that may change in the future, too.

I don't want to come off as harsh or unhelpful, but perhaps the reason nobody replied before was because you have so many questions, and many of them are either rather broad, very VERY broad, or at least would require much effort to write a detailed enough post to cover all the possible answers to your question. I'd suggest doing some research about the many topics you're asking about so you can formulate some more specific and educated questions.
I myself do not know the specifics of non-NTSC conversions, but I will say that I believe you have 60i and 60p confused in your example... 720p60 can easily be used to create 60i content, and could also be played at 30p to act as a half-speed slowmo.
Perhaps some people with more experience in standards conversions and theatre/festival formats will find the time to chime in, I wish you luck.
