There are pluses if done right. Zero compression, native frame rates as opposed to NTSC-PAL blended frames conversion, the possibility of progressive transfers, better colour definition if mastered from the original video source as opposed to using the DVD masters, and of course lossless audio. That plus more episodes on scratch resistant discs makes me think every time about upgrading to BD even for SD transfers. But then you sometimes get over DNR'd Q-Tec smeared rubbish which makes you stick with the DVD.
