 Replying to [comment:4 kierank]:
 > If the user asks for a timebase of 25 they should get a timebase of 25,
 no?

 yes but he is asking for a frame rate of 25 not a timebase


 > He/she's just making the point that applications don't like this weird
 timebase.

 The problem is with a timebase of 25 audio and video frames cant be synced
 more precissely than within 1/25 sec. (yes some user did complain about
 this and no edit lists didnt work)
 It would be interresting to know if theres a timebase thats more precisse
 than 1/25 and still works with all applications
