Is there any possibility that the vcr, tbc, or DV capture box (Pyro) could get so confused by a burst of tape noise during capture that it could end up silently dropping a FIELD and capturing two odd or two even fields in a row before continuing with the field order reversed?

I'm asking, because I just finished encoding my first capture made with both my new TBC and Pyro using HCenc & burned to a DVD, and I've noticed that it has spots where everything seems to be fine (even with fast and medium-speed motion), and spots where the field order seems to be reversed (vibrating badly, even with regard to slowly-moving objects).

If that's the case, is there any way to fix it, besides maybe trying to adaptively deinterlace it, then re-interlace it with proper field order? And if I DO have to deinterlace and reinterlace it to fix it once and for all, what are some good filters known to work particularly well with content that's NOT telecined film (ie, video from the start)?


(update) It looks like field-order reversal wasn't the problem, after all. The whole frame was jumping vertically. I've mostly managed to fix it using DePan and Avisynth (with frequency-limit set to somewhere around 8-12... still experimenting... too low, and the whole screen bobs around a motionless dominant center object... too high, and it doesn't fix the problem)
