I am using Adobe Premiere 6.0 with a JVC GR-DVL510U using MS DV(NTSC), Frame rate 720X480 @29.97FPS Depth millions and quality 100% using DV Device Control 2.0 . For some reason all of my captured video has a lot of lines in it whenever there is motion on the video. When the video is still or slow it isnt noticeable until the person or object moves again. It is a huge annoyance. Does anyone know how to correct this? Replies are very much appreciated.

Lots of lines in captured video

Where are you judging picture quality?
Are you basing your judgement on what you see in the Premiere Program Monitor window? If so, then you are seeing interlacing artifacts due to showing interlaced footage on a non-interlaced computer display. Try viewing the footage on a TV fed from the computer to confirm this diagnosis.
If you are already using an external TV and are seeing such lines, then there is an issue somewhere else, but let's cross that bridge when you have answered the first question.

I am viewing it after I have captured the video and saved it to a file. The file is run in Windows Media, Winamp, any video viewing software, you get the idea. An dthe lines are still there. This is an idea of what it looks like:
It looks pretty much like that but not as blurry and it only appears that way when there is motion in the video. The more motion the more it looks like this

As I suspected, these are interlacing artifacts caused by movement between the two fields of each frame.
If your final target is a computer display, then somewhere in the processing chain you need to select 'no fields' or 'deinterlace' depending on where you do it.
If your final target is tape/DVD/TV, then when you view the footage on a TV, with its interlaced display, the 'problem' will disappear.
If you have PhotoShop or similar image program, then see for yourself what happens when you deinterlace a still.
Or export a still from Premiere having first opted for 'deinterlace' in export settings for stills.

Comnpression of the image for the web destroys the interlaced field information, so it is not possible to oeprate on your image at a distance.
'It' isn't sufficently descritive to make any sense of your reply. Just what have you done and what was the result?

What you are seeing is interlacing artifacts, as I have already explained. To remove them, you need either to view on an interlaced display, or to jettison one of the fields.
If you export the timeline intending to view the result only on a non-interlaced computer display, try 'no fields' in the export Keyframes and Rendering settings rather than deinterlace in special processing.
Be aware that exporting stills from interlaced footage always generates such artifacts, even if they are not too obvious sometimes. Well worth seeing what deinterlacing does for still image quality. But this does not mean that you should deinterlace moving images without good reason.
