video editors can handle HDV... You need to connect your camera (using the DV port) to your computer's FireWire port with a FireWire cable.
You may need to buy a FireWire cable - and you may need to add a FireWire port to you computer (Macs have had FireWire ports for years; Windows machines do not commonly have a FireWire port).
Your camera's operating manual discusses connecting to a computer starting on Page 64. If you don't have the manual, download it at canon.com http://alpha02u.c-wss.com/inc/ApplServlet?SV=WWUCA900
Software:
Macintosh: iMovie HD 5 and newer; FinalCut 5 and newer
Windows: Adobe Premiere, Sony Vegas, others...
I bought the Canon HV 10 and the video looks amazing on my HD TV. But I dont know what software to use to edit and view my videos on my computer. Any suggestions????
