I'm assuming you're using the following programs to edit and record.
-Sony Vegas 12 or Movie Maker
-Dxtory (Kind of obvious)
As you already know, the water mark is in the way. There are recording programs such as Camstasia or Fraps where you're able to download them for free, just use Youtube.
Your editing/syncing was barely noticeable, it was just mashed around with decent clips to some music (not too sure if that's what you were trying to do that or not)
I'm assuming you're playing in small screen? If that is and you are using Sony Vegas 12 to edit, right click on the video clip next time, there you can find something that'll saw Switches I believe and then Maintain Aspect Ratio. You want to click on that so that the video will take up the whole screen.
Overall the mini-montage was very bland, nothing too exciting, the watermarks got in the way, etc. For a beginner (I'm assuming) it's okay-ish ;c
