Well its a shame, i mark any hardsubbed film as a nuke and watch out for an unmarked proper. I mean its better than nothing.
Incidently, i mark rips with dubbed tracks as nukes for the same reason, although there are least you don't have the picture obscured.
The problem is the picture is permantly defaced, and if there's white background you don't get the contrast. Not only does it not ruin it if you only rip softsubs, you have control over the positioning and settings of the subtitles too. So even if its only for an english audience, i still don't see how hard subs are anything but a bad thing. This is from a guy that can only speak english so I don't think the english audience only is true, you loose too much with hardsubs, and not only that, its really bad for compressibility. Xvid is very bad at sudden changes in colour, and it takes the same knock out of the quality as not cropping does. (Hence why its a forbidden in tdx)
Shame really, Kamuix rips some great movies
