Sweet, thanks.
[EDIT]
I actually found a solution to this.
When I was packing my textures i was putting them flush with each other.. next I tried putting a gap between them. both had lines in the rendering. So what I did was this. I left 5 spaces between each texture, when I copied the original texture onto the new master packed texture I simply copied it 5 times, once one pixel off in each direction and then exactly where I wanted to set the UVs, this gave the blead off pixel the same colors as those directly on the UV bounding box, and looks great now.
with mipmapping on I have to extend the overdraw to about 5 pixels in each direction !
