I need to turn a professionally produced mxf file into a blu ray disc for distribution to tv stations who cannot get our satellite feed. It needs to carry closed captioning. (50mbps)

How do I render and burn to blu ray. Multiple attempts have failed. I have dvd architect 5.2 and sony vegas 10 with 64 bit platform. Been a vegas editor professionally for 8 years.

Need to know the work flow..... I saw a tutorial that indicated that the only way to keep line 21 closed captioning is to render in the mxf format.
