Some DVDs have no sound with bluetooth heaphones

Solution
Are the DVDs purchased or burned? If the latter, that could be your problem.

Also, have you checked the sounds while trying to run the DVD that gives issues. By right clicking on the "Speaker" icon in the task bar and then click "Open Volume Mixer". In this window check the sounds for the program that the DVD is running through as well as the headset.

You may also wish to update the drivers.
