.MKV data burn directly to BD50

[doobre]

Hi there, as it says above, I have been successful many times in the past, but each time I have this task to do I seem to have to go thru a 'hit or/and miss' process everytime, usually it complains about the available size being insufficient.

Often I have to restore all defaults several times, and /or open and close the app several times, eventually the the app will accept the .mkv file and it will burn.

Is there a definitive procedure that will work everytime?

A related question: what is the usable free space on a BD50 when burning data directly?, & Is the size calculator within Imgburn accurate for direct data burning extimations?

cheers CD
