   zoom, zoom, not

   I'd try slowing the router down and using a backer (or, fronter) board to reduce the tear-out. I move from left to right on the jig.

   Does the bit have to be narrower than the cut?

   If the bit is buried in the wood then one side of the groove is being cut in the wrong direction. Is it better to take multiple cuts with a narrower bit?

   Is plywood a bad choice for dovetails?

   bit size vs. tail szie

   I use a PC 4200-series DT jig in conjunction with their recommended bit and guide bushing. There is a slight about of lateral play when making the cut, so I track the bushing along one side, across the back, and then out the opposite side of the template openings.

   And, I'd say, yes, plywood is not the best choice for dovetail joints.
