Interlaced DVD to desinterlaced .mp4

Hello everyone.

So I need someone to help me out here, I know this probably has been asked hundreds of times but all the threads I've visited neither seem to solve my problem (I'm probably too dumb).

I have hundreds of DVDs from movies (old and some not too old) that I need to convert to mp4 for streaming on a website, the problem is that I don't know which settings do I need to use to have the best results.

Here's the media info from video_ts file:

I'm using the latest version of Vidcoder (works pretty much the same than Handbrake).

And here are the settings that I'm using for the encode:





So, am I doing this correctly? Is it wrong? Do I need to change to VFR? Is it OK to leave the same FPS? Is BOB the best desinterlace for this kind of movie?

Thanks in advance for all the help.
