What does Canon say about Mac support on the product page for that camcorder? Also, what did Canon's tech support people say when you asked them this same question?
All I can say is that you can probably be sure of at least some very basic support, essentially turning the camcorder into a mass storage device and copying files off. Whether or not you'll have any specialty software to try and make the process simpler will depend on the answers to the above questions.
I am looking to buy a good quality HDV camcorder, and have found that the Canon XHA1S is most suitable to my requirements. However I have a Macbook Pro - and I'm new to Apple products.
Can someone tell me if this camcorder would be compatible with the Macbook Pro
