[A better way to smooth out edges?]

I have been trying to make backgrounds and sigs but unfortunately all the pictures that I remove backgrounds on become very rough around the edges. Soften portrait works a little but it's not good enough and feathering and duplicating doesn't really seem to get me anywhere. Is there a better way to do this?

[Watermark on a video]

Hi all, i was just wondering if anyone knew how to put a watermark on a video? In Windows Movie Maker or Vegas, both would be nice though. I was looking through the search and I couldn't find anything on this, just watermarks for pictures so if anyone could shed some light on this for me I would greatly appreciate it. Thanks!

[Photoshop Brushes]

I downloaded Paint.Net in December, can I use Photoshop brushes in this program or do I need some sort of plugin?

[Userbar font?]

Thanks, unfortunately none of those seem to be it, I suppose I'll just have to keep looking.

[Userbar font?]

Hi guys, I'm new here and to paint.net. Love the program btw, much easier for me to use than photoshop. Anyway, I was wondering if anyone could tell me what the font is that's mostly used in the glossy looking userbars? The one thats like...an outline, I'm not really sure how to describe it lol, but if anyone could point me towards that font, I would be totally grateful
