oh I don't know about MAC, but I'm using a free software and I'm happy with it. It's called Videopad editor. What it's missing though is some nice text effects, and I think iMovie is much better for this. I need to find a way to make a proper video intro, but haven't found our how yet.

With regards to quality over quantity, that's my eternal struggle. I don't want anyone to watch my videos and think "this is total crap", so I'm careful with my content...but I do the same with written posts, so I guess it's just my rhythm too ahah. Anyways great to see you more on dtube now!
