Fluid slowmotion control?

I record my son’s games with a videocam and I am thinking of burning this to DVD and I would like to know if there is any DVD playback software that has “fluid” slowmotion features that will allow me to view the action in slomo just like what you see on Sportscenter with the NBA/NFL e.t.c? Thanks.
p.s. I would like to be able to control the slomo by moving the play slider myself if possible, have tried a couple of these programs but when I move the Play slider the scene does not move fluidly, it looks “jittery” or choppy.
