Im a little confused in regards to the "Fields" aspect being upper, lower or none. When i burn a DVD which field would anyone suggest. I burn DVDs for TV and PC viewing if that helps. Thnx

From your other post, you say you are capturing DV from your camera. DV *always* uses Lower Field First. So as the primary rule of thumb in video editing, you MUST absolutely always use Lower Field First throughout your project, when you go to create your new DVD-compliant mpeg-2 from the edited DV project, and when you burn your DVD.

Similarly, if you start with video from a mini DVD or hard disk camera, it is usually Upper Field First, so you use that throughout the whole project.

Frame Based (no fields) is a little different. It is normally only used for viewing on computer monitors or the web or progressive scan digital TVs. But the latter will also read DVDs which use Upper or Lower Field First, and you should continue to use either of those, particularly if you intend to distribute your DVDs to friends who may not have progressive scan TVs.

Yes, as Ken says even if one has a Progressive Scan HDTV you still stay with LFF or UFF fielded video because that is your source videos video specs.

Progressive Scan HDTV is a "Display Mode".
The playback device (Blu-Ray disc player or DVD player setup as progressive scanning) will convert your interlaced videos to Progressive.
You cannot do it in software unless you double the vertical refresh rate, which then will display each field as a frame. However this isn't compliant for standard dvd's.

Some consumer camcorders can record in this mode, like the Canon HV20 can record in 24P. Semi-Pro and Professional cameras can also record progressive video.
