I have used the HC3 for 2 days with iMovie and iDVD on my mac mini.
When i started to import the footage with iMovie, i started to do it manually, moving forward and backward between scenes. This caused iMovie to crash very frequently. I then chose to let iMovie import the footage by itself and everything went fine.
I then easily added the chapters, transfered to iDVD and created a DVD with menus in 1 hour. I am really exited about how fast i was able to create a very nice DVD.
However i am trying to convert the footage from iMovie into a small (100-200 MB) in a 16:9 format but I am getting very big files that are not as sharp as the original or some other examples i saw on the web such as the examples in this page about the Sanyo DMX-HD1:

Would you have any recommendation about the settings to export in quicktime or other format? Which video codec provides the best quality/size ratio? H.264? MPEG4?
