I'm not entirely sure I know what you mean about manually positioning the solve for a blurry shot?? Do you mean how can you track a blurry shot?? You can manually place the tracking locator for every frame if you need to - not every shot you come across (in fact, very little!) will you give you perfect points to track. If you have a very fast moving shot with motion blur, you can manually place the tracking locator for each frame for where you think the centre is, obviously you need to try to be accurate.

Could you post a screenshot of your Maya scene with you solve/geometry at all? I could give you some better advice if I took a look, or feel free to email it to me.

..it would be quite cool to create a vid on this, but I'm pretty busy at the mo, moving house in a few weeks, so things are pretty hectic at the mo. Glad your learning lots though, sounds like you are picking it up really well to be good at tracking takes a lot of practice and patience.
