Heya Matt
I'm not familiar with her DVD, but I have her book 'Real Fast Indian Food' and all the recipes in it are excellent, some of the nicest I've ever had whether cooked at home or in a BIR.
As you say her style isn't really BIR, but more authentic home cooked Indian food as the Indians themselves would cook for their family.
Her recipes are highly recommended in my opinion, so I'm not surprised you've had good results yourself.
Cheers and good Karma!
