The software that you are planning to use will indeed work with your AVCHD videos in their native format, and burn a Blu Ray disk, but if you aren't wanting to do a lot of editing of your videos, there is a much cheaper option to using that program.

AVS video Converter

Their software is known for ease of use and it's what I use for almost all my conversions and burning. They do have an editing program as well that you can get more info about on the link provided. It's called AVS video editor. I don't currently use this program, but it almost certainly would be easier to use. It may be worth checking both of these out since you can get a full working version on a trial basis before having to buy them.

Hope this helps. Please don't forget to accept and leave positive feedback if I've been helpful. Thanks.!!!

No problem. The Sony Vegas Movie Studio HD Platinum 11 has AVCHD support for Sony camcorders. You can import and export the AVCHD files in the program as well as edit them. I do have to be honest though, I haven't done it myself, but I deal with files conversions and DVD authoring on a daily basis ans as long as the specs and features of the software can be believed, it is capable of doing exactly what you are wanting to do. I still would prefer the AVS program just because it's the easiest to use that I've ever seen anywhere, but the Sony program will work for you. Thanks for the accept and let me know if there's anything else that I can do to assist you. I'll be here when you need me.
