Extra training

I have been boxing about a year and a half now. I've had 3 bouts 2 wins 1 loss. I train 3 times a week with my trainer at his gym. But the problem is it's quite a journey and sometimes I wonder if I'm actually learning any new things. Ive now got Acces to a gym 2 minutes away from home with a ring, bags weights gym ect which I go to between sessions with my trainer. I was wondering if there are any decent self training DVDs for fighters that are not beginners that I could to practise and learn new things when I'm in the other gym.
