Why don't you just use Image Converter and Movie Player? Smaller file sizes and much better video quality, plus it is already in your NX73's ROM. All my kinoma videos come out blocky and the mono sound sucks. Try Movie Player, you'll be much happier.
im going to play devils advocate for a bit and say that kinoma can be better now that the later models that can use CF cards (and those with MS PRO sticks) can hold more than 128MB.
My movies (usually I use it for watching movies or music videos) can produce sound in stereo, full screen and with much higher clarity before and I dont have to worry about fitting it in a 128MB MS stick like I used to do when I used my NR70V. For example I had to break a good version of SHREK on 1.5 128MB sticks...but on a 256 or better yet..a 512mb?..the quality should kick ***.
But to be honest, I just got my Nx70v this weekso I havent used ImageConverter and MoviePlayer yet. (i'd like to be able to see it on landscape mode if it indeed has one available)
