I have Magix Video Easy to edit my Canon HG 10 HD videos without any problem. However, Magix Video Easy does not recognize the .mts files from Sony Handycam HDR-CX550, which is a new AVCHD camcorder for me. I do not use Adobe Premiere, because I am not a professional for editing. Magix is good for me with low price. - Andy
