Rice with Veggies - Really good

I wanted to make some rice in the pressure cooker to go with the grilled pork chops that we had for dinner tonight.  It was definitely a learning experience but it turned out really good and next time it will be even better.  What I'm picking up on is that what the user guide says about how long things should cook is completely unreliable.  This is really frustrating to me because I don't know what I'm doing.  If I can't rely on the user guide to give me a good idea of how long to set the cooker for I just have to learn by trial and error.  Arrrggghh! 

The recipe called for brown rice and long grain rice.  The guide says that brown rice needs 17-20 min and long grain needs 7-8 min plus there are fresh veggies in it.  The rice setting on the cooker is 10 min so the plan was to start it with the liquid, seasoning and brown rice for 10 min.  Then add the long grain and veggies for another 10 min cycle.  The problem was that the long grain wasn't done at the end of that second cycle.  It was crunchy crittters! So I poured in a little more broth and ran it another 10 min cycle.  At that point the rice was all nicely done but the veggies were way overcooked.  Argh! 

Brown Rice with veggies - Pressure cooker
1 1/4 cp brown rice
3/4 cp wild rice
2 1/2 cp chicken broth - low sodium
Garlic powder
Onion powder
2 bay leaves
Black pepper

3 Tbls butter
1 green bell pepper, chopped 
1 red bell pepper, chopped
4 med carrots, sliced 1/2" 

Put the chicken broth in the cooker and add the rice.  Add all of the seasonings.  Set for one 10 min rice cycle.  Release the pressure and add the butter and the veggies.  Just leave them on top and do not stir it all together.  Set for another 10 min rice cycle.  

This is slightly different from the way I cooked it tonight.  I want to try it with the wild rice once.  After that I may just go with straight brown rice.  I don't see the point in mixing the brown and long grain.  

EDIT - I made this again and it turned out perfect!  The rice was cooked, nice and fluffy and the veggies were perfect as well.  However I think I'll try switching up the veggies a bit.  Leave out the green pepper, more carrots and maybe whole pea pods
