Yet another technical question

[Lee]

When I recorded videos on my old digitial camera, they always played back using Quicktime (which Apple/iPods use) on my computer. Now with my most recent camera, a Pentex, when I play back videos, it uses Windows Media Player. My question is, how can I get them converted to Quicktime, so I can put them in my iTunes & on my iPod? I have a 4th generation iPod; I don't know if that makes a difference or not.

Thanks.
