I have reload P2G 12 several times. Used V 11 up until recently but have notice that if I input mpeg or mp4 say 40 gig and use "Smartfit" or use less than disc size the then try to burn to folders it forces a size much smaller like 4gigs as though defaulting to DVD size. V 11 ran well for awhile but started doind same. I create some of the video using APPLIAN video capture and media capture program. Not sure why this changed. Would like to use program to put more than 4 hours of less resolution video on Blu ray.
