well to each there own,but mkv does not suck,I used to think that but not anymore,and I am not going to re-encode all my raw HD files and then upload,that is just to much damn work,I will get better results with my full untouched files anyways,plus I have to many projects on my plate now.
just upload a 1-2 min mkv file with the audio/video and let me take a look at it,you are making 1080p AVCHD's right?
