The mystery of 00009.m2ts

[kuchikirukia]

Has anyone ever seen a Blueray with a garbage m2ts file? I've got one that has a duplicate interview segment with a stream broken up by sections from another Bluray.
The 00009.mpls playlist glitches at certain points. Go into 00009.m2ts and, lo and behold, there's segments from an entirely different concert in there. It's progressive as well, where the interview is interlaced.

I'm surprised it even plays.

That points to a bad ripping (I don't dare to say bad download :) , oops)

Yup, mystery solved. It created the m2ts over the deleted remains of the rip for another encoding, so when it borked, I not only got to rewatch it, I got to see how fragmented my filesystem is. (Because holy crap those segments were out of order)
Since both were Vocaloid concert Blurays I thought it might have come from their end. I wasn't expecting to see 25Mbps clips in 1080 when I store 6Mbps in 720.

NTFS, you so silly.
