Thanks for your interest, Bill.
I'm running 1.46 GHz and 2039 MB of RAM, which is not very strong and why I have to convert the HD files to AVI or WMA -- the computer can't handle the AVCHD files. (I'm already looking around at something stronger, so feel free to offer suggestions in relation to GHz, RAM and so on...) I use Wondershare to transfer, which seems to work great, and the last test I did with sound there was no cut out. Only outdoors did I notice cut out on the clips. Maybe this has something to do with the auto wind reduction feature?
My immediate goal is YouTube, but a lot of material would like to be able to put on DVD later.
