Can one follow Hinduism and Buddhism at the same time?

I am born Hindu and have been following Buddhism for more than a year. The change has been a life changing experience but now I find myself at the junction of two religions. I sometimes face contradictory situations where its ok in one religion but violates the other. Traveling in two boats at the same time is certainly not possible but its also difficult to choose one over the other. So my question is:
1) Can one follow Hinduism and Buddhism at the same time?
2) How to maintain a balance between the two?
3) Or would I have to choose one over the other?
4) Or is it possible to choose Buddhism as subset of Hinduism, just like Jains do i.e. the mainly follow their own religion first & then they following Hinduism. So even in contradictory situations, they choose Jain rule over Hindu rule.
