Hey I have alot of MKV video files which are pretty high quality, however Vegas doesnt work with MKV. I used this converter http://www.arcsoft.com/topics/others/h2 ... erter.html to convert MKV into many different formats. However when watching back the videos on Vegas all were very laggy and even when I rendered it was pretty much the same. How do I make sure the picture is not much different to the MKV file i.e use another program or what? I dont want to pay for one though.
