I have freeze problem with Blu Ray disc in VMS13 ( same in VMS16). Video is of theatre show in 2 Acts. First is 90 mins second is 45 mins. For past shows of similar length , have made both DVD and Blu Ray versions, one disc for each Act. Never had this problem. I have 23 scene selects in Act 1 and about 16 in Act 2 ( Scenes associated with each song start) . DVD discs play without issue, but Blu Ray freeze at about scene 22. After many tries, I split the whole show into equal length sections each just over an hour. Again find the (Act 1 pt 2 plus Act 2) disc freezes just after about 22. Tried one without scene selection ( rendered in VMS13 and sent to DVD architect to make a Blu Ray) and it too freezes about same place. The file sizes are only about 16 -18 GB well within a single layer Blu Ray disc capacity. As I say, done these shows this way for 4 years and this is first time. Can anyone suggest how to overcome this? The discs have the freeze issue on different brand Blu Ray players but not in PC.
