Field Problems when rendered

So I've been having this problem for a while now, and I'm getting tired of it.
I use MBE2 on a lot of different kinds of footage and find the filters to be very good, except for when I use it on MiniDV 30i footage. The footage renders fine but when I play it back to an external monitor(TV), the fields are off. I then have to run the shift fields (+1) filter in order to correct the field order and sometimes I get artifacts in my footage. I know I'm capturing the footage correctly because this only happens when I use MBE. My fields are perfectly fine without the filters.

Anyone ever encounter this? It would be a big help if someone could solve this problem.
