I would convert to Mp4/AAC. That format is almost globally compatible with other devices. It is a delivery format good for viewing. Because it is compressed, thus saving space, it is not as good for editing as some other less compressed formats that consume more space, like .dv, Pro Res 22, AIC, that are better for editing. However, for anything other than perhaps professional purposes I have found that Mp4 edits just fine. The AAC part is Advanced Audio Coding that also is more compressed than, say, .aiff. But for my consumer movie purposes the sound is just fine.
You can use the free download Handbrake to make the conversion to Mp4/AAC that it will do by default. You can get Handbrake here:
