..and preferably QT Pro for the added functionality.
Also, the MOV format is but a container, and it's the CODEC inside that matters. Do not know what options your JVC has along those lines, but you should be able to choose a CODEC that will have been installed with the most recent QT, as John T. mentions. For a bit more background on MOV, this ARTICLE might help.
I also agree with Craig that the US$ 29 upgrade/unlock for QT Player to Pro is worth it, and the additional functionality might come in handy.
PS - note that there ARE some MOV CODEC's, that are for the Mac only, but most are X-platform, so long as you have the proper CODEC installed on your system, and the JVC is very likely to use the X-platform choices.
If your camera is capable of outputting anything else than MOV, do not use MOV. It completely destroys the 64 bit nature of CS5 and leaves you with 32 bit processing with a very troublesome codec. Nobody in their right mind would use anything QuiRcktime if they have alternatives, at least with CS5.
