Kieran, the material used in testing is CFR to the best of my knowedge
the material does not start at pts 0, the code ignores the start time
aka the first pts. Theres only one possibility to fix this and that is
to use the first pts, no (de)telecine operation can maintain sync

this is not what i am talking about
