Upscaling

I'm playing with upscaling some of my DVDs (the ones I want in higher quality than normal) from 480p or 480i to a couple of formats: 480p60, 720p60, 1080p60. There's a couple of reasons and *theories* that I have about doing it:

I *have* to encode my source video at some point, because I can't *consistently* get a DVD → VOB or DVD → MKV lossless copy somehow that is clean, and doesn't have playback issues somewhere, at some point (sadness). I could write more code to do it myself, but since there's so many tools out there to encode it, and I don't want to debug my own, I'm passing on it. So, encode we must.

Another reason I *have* to encode is that source material is interlaced or telecined, which needs to be fixed as well.

Playing back video that's a 480p source on an HDTV (my Sony rear projection TV is 1080p) is going to get displayed at 1080p resolution anyway, so why not go ahead and do it myself instead of having their software zoom for me? This is the argument that makes the most sense to me.

I like the idea of having a constant framerate (60fps) over a variable one. In my mind, it just makes more sense, it gives my warm fuzzies, and I've *always* had problems from day one trying to figure out VFR and the film → video transitions when encoding stuff, especially with TV shows on DVD. I'd rather just have one constant framerate. Going to 60 makes more sense than going from 23.97 or 29.97 to 30 anyway. Might as well double it so there's no minor weirdness there (again, makes sense in my head).
