Chuck there is one more thing you need to look at and that is stock preparation. The stock needs to be square and straight. If the stock is not straight then you will never get the joints to closeup correctly because there is already error in you angles to start. The Lion trimmer is a good tool but if the stock is not straight then you still have the problem of registration to the blade.
Looking at the picture of your joints my first thought is that your blade might not be parallel to the miter slot and/or your blade is not square to the table. I would also make sure that there is no slop in the miter gauge bar in the slot. If the alignment of the saw and miter gauge is correct then I would look a possible blade deflection or vibration. Also make sure you don't overfeed the stock, this could cause problems also.
