Are you seeing this dropout on the computer monitor, or attached NTSC/PAL Monitor? You cannot judge the quality of the image, or scrutinize if for dropouts on the computer monitor. If they happen on the External Monitor then it is an issue. If it happens on your computer then it is the usual lessening of quality that occurs so that you can see all the frames:

DV footage requires large amounts of data and many computations. In order to maintain frame rate and be viewable at a normal size, only about one-fourth of the DV data is used in displaying the movie to the screen. However, the DV footage is still at full quality, and is best viewed thru a TV or NTSC monitor routed thru your camera or deck.
Don’t forget, the viewer is a viewer, it shows you what you have. The canvas is also a viewer AT THE RESOLUTION YOU SET.
