Premiere Elements does not support 24p video at this time.
For 24p support, you may need to upgrade to Premiere CS4 or CS5. Sorry.
As for your other video from still cameras, that will likely need to be converted, per the FAQs to the right of this forum.
More details why and how to convert video can be found in my Steve's Tips article at Muvipix.com.
I'll have a go ....
1) I'd like to know that as well. There was thread (http://forums.adobe.com/thread/605768?tstart=0) that dicusses non-standard presets that may work with some DSLR formats. I have not tried them though.
2) Again, I'd like to know that as well. You can output from Pre8 to a AVCHD file (.m2t) using the Share -> Personal Computer -> MPEG -> H.264 1920x1080i 25. You may be able to copy the resulting file to an SD card, or write to a DVD using another program which may or maynot create the Blu-ray folder structure on a std DVD.
3) I'd try changing the .MOV file extension to a .m2t or .m2ts or .mts and see if that works. Renaming the file works fine in Win 7, don't know about Bluray players though.
4) No idea but using Gspot or Mediainfo may at least confirm what codecs are needed. The standard presets seem to stick to the DV-AVI requirements pretty closely.
Your current CPU might not be upto the task of editing AVCHD video. Everything I've read indicates a powerful CPU and subsystem is needed.
As Steve suggests - Premiere CS5 might be the answer, I can't justify the cost though. Maybe Prem Elements 9 ????
