Thanks for the tutorial, but let me tell you why its such a bad idea. First of all, its not going to enhance the quality of your picture. Secondly, its gonna take much more space than actual resolution DVDRip in x264. And lastly, it takes a huge amount of time to convert it. We're talking about 12 hours or so. And at the end, the output is gonna look exactly same, except the fact that we've the movie with stretched output which your Video player was going to do at the runtime of the movie.

Thanks for your efforts though.
