Can you share more information please at which parts of software the changes are required? I maintain all Nvidia related stuff for one of distros trying to keep same day release so would like to know earlier what will be changed and where: driver/vdpau library/players and if this change will break compatibility with present vdpau infrastructure. Sitting at night and rewriting package code in hurry is not I like to do.
