If I understand your question correctly Ron, you have some .mov or .mts or similar files on your PC. When you click on them they play as video and you want to create a DVD that will play on the DVD player you have attached to your TV.
Like audio CDs, video DVDs have a special format, they are not just a string of files. In order to create this sort of DVD you need special software. It could be that the DVD writing software that came with your PC will have a "create video DVD" option (my PC does, my laptop doesn't). Failing that you will need to get hold of a video editing package that will allow you to produce a DVD. I'm sure others will know of free ones that are available.
