Taken from the Gamecube version of "Phantasy Star Online: Episode I & II", these specific, new (in comparison to the Sofdec files in the original Dreamcast version of PSO) videos, psogc_j.sfd and psogc_j2.sfd, don't seem to use a discernible MPEG stream for it's video part -- since they were unable to be demuxed or even played through an MPEG/Sofdec player of some sort. Believe me; I tried all there was, but to no avail.
Oddly enough, however, one of the new videos, the "animated" Normal Ending background (ending_normal.sfd), actually is a readable MPEG stream.
Basically, I would kindly please like for any of you guys to help examine these files for me, because I need their video streams for something I'm working on.
The files are arranged differently. The information for the file is at the end of it instead of near the beginning. Should still be either m1v or m2v however. I'll check with something else to confirm.
Ended up renaming the files m2v and they became playable(m1v also works). No sound data i could find, however.
