x262 MPEG-2 encoder in commercial DVD production?
Hi. I think I've found a DVD I bought, which was encoded with x262.
The movie is "L'ULTIMA NOTTE DI AMORE" (2023). This is the mediainfo: Code:

Given how widespread x262 is in Italy I wouldn't be surprised.
What I'm surprised to see though is that they didn't stripe off the writing library as it's generally done instead. |

(sometimes I think of VC-1 as the final spiritual successor of MPEG-2/H.263, with H.264 as the first of a new generation of codec approaches). |
