For comparison between BluRay and DVD: I did something similar, also for an animated series, for DVD. I took DVDs from Japan, ripped the video, and inserted good subtitles (the original subtitles for the series as released in the US were trash), and burned to DVD. The hardest part was making sure the subtitles were in sync. After that, a simple shell script and dvdauthor were all I needed. With some modifications, this shell script could also take speedsubbed episodes and produce DVDs containing between four and six episodes per disc (this was before streaming simultaneous releases). To address a question from mrec above about why physical media was chosen - I was making this set of discs for a friend for a lending library for their club. The easiest way to move video around at the time was DVD (this was right as BluRay was taking off). Having the disc images was also helpful in case the (relatively fragile) DVD-R media got damaged while it was lent out.
