Any video intended for playback on TV should be captured and encoded as interlaced. Deinterlacing it will reduce the quality, even make it appear choppy.
Take a look about 1/4 of the way down the page:

Because the results will be a little better if you leave it progressive.
If you take a non-interlaced source and convert it to interlaced MPEG2 for DVD, the MPEG encoder will split the two fields apart and encode them separately. This results in more blurring of the colors (although this is usually very subtle) and less efficient compression.
The general rule: interlaced source -> interlaced MPEG2 for DVD; progressive source -> progressive MPEG2 for DVD. -
I would answer that last question with "not necessarily".
This is one of those situations where answering one question leads to many others. To understand the answers you have been given, and the reasons why, you really need to round out your knowledge base.
I would start with reading some of the definitions and guides available on this site, the answers are already there. The reason they are there is that questions like this get asked several hundred times a year.
The answer you have not gotten yet is that you should leave interlaced for TV playback and de-interlace for PC playback, generally. A few minutes of reading will tell you why. -
