Huh... It's kind of interesting to see this turn into a topic about video quality.
I try not to judge too harshly on video quality, but if the video's size (not to be confused with file size) is smaller than TV-N or uses a similar/worse compressed encoding, I probably won't bother. Might save the the soft sub files in case I get a better raw source, but that's about it. Really, I tend to judge a release based on how it will come out when I watch it on TV, because watching things on a TV set is a novelty that still appeals to me, my family, and any IRL friends I've made. Here's how I start my judging process:
1. I watch the subbed videos on my computer just as a preliminary watch, making notes of what I did or did not like. (like if there is fuzz or digital noise, etc.) This part isn't too important, it's just something to put in the back of my head just in case.
2. I put as many different file formats into a flash drive; softsubs, hardsubs, AVI, MKV, MP4, you name it. This will keep the video's original quality without having to compress it, resize it, or whatever else that might compromise what I all ready have.
3. I hook up the flash drive to the TV. Since I have a Standard Definition set, this usually means me using a device that will recognize the flash drive and its files. I mostly use my XBOX 360 for best results, but I have others that are just as good. EDIT: To be clear, I do prefer to use an SDTV set to set the bar. I've heard most HDTV sets tend to auto-correct or compensate for any flaws with the video source anyways.
4. I play each file side by side to see what it's like, but I compare similar things to each other. I'm only going to compare an SD release against other SD releases, same with HD (that includes 720 and 1080). I will not compare an SD against an HD.
So far with TV-N, my 360 can never play their SD releases (which are usually AVI) correctly. Not even their newer stuff comes out right. The audio gets out of sync every time, and the colors are all messed up. Bright colors are too bright and bleed out in glaring ways, dark colors are usually too dark, there is lots of glare and blur, etc. Their HD releases are usually better in all those fields, but not always.
With groups like Over-Time and whoever else, I never have a problem watching their stuff on TV. The audio is always in sync, the colors feel exactly like what you should be seeing if you were watching it air on TV for the first time, and so on. In fact, with certain groups, any minor problems I may have had with the video source disappear when I'm watching it on TV.
And even then, the releases I get from most softsubbers tends to be great even on computers. With TV-N's SD releases, I can always see a little bit of fuzz or blurriness. With the SD releases of most softsubbers, I can make out details MUCH more clearly. For example, with Over-Time's SD releases, I can CLEARLY make out every detail in a Kamen Rider's compound eyes. I could never do that with TV-N's version. It also probably helps that the video size of Over-Time's releases are usually a little bit larger too, probably closer to what they should be. Even with slight changes in quality, these circumstances usually hold true even when I comparing TV rip against TV rip, or DVD rip against DVD rip.
To anyone who would ask why I even bother with SD releases in the first place... I'm old school like that. I'm not going to download an HD version of anything in the first place unless it's worth my time (like the Super Hero Taisen movie).
