Thanks again for the reply. As I mentioned in an earlier post there are some portions of my video that defy de-interlacing. Some looks good, others look like viewing the scenes through a screen door - all with the very same origination. Perhaps you might take a look at my other topic Technical Discussion: Interlacing Revisited
Download the two photos there and enlarge them to full screen and you will see what I mean.
In 2007 I bought an HDV camcorder which records in 1080i and I never have a problem with the interlacing. It always looks good.So, not an issue there.
