That's a pretty good burn. Does your set top player agree with the last 20% of that video? I ask, because my particularly picky DVD player will get stuck, jammed, and go bonkers over TY medias unless they are burned at 4x.
Anyway, the disc is nicely within spec when read back on your BenQ, but not all players read so nicely, so do check usability with other players.
Scan is only 1/3 of the story, but your scan is very nice.
