Hi - Now that's a revelation! The V-Pad "help guide" is woefully inadequate as for informing the user of traps like that, the actual file format that's required for BD, (which I've since learned is restricted to UDF 2.5 or 2.6 only for blue ray), and many other useful and necessary details.
ISO to hard disc,later burned, or "Blue-ray Movie," or "Blue-ray Data Disc" files, created with an mp4-from-sequence file, (which plays well in VLC), all fail in the home player. Mostly massive drop-frame is the result. The only burn success is: making that export mp4, taking care to have the encoder settings conform to BD, (29.97 fps, 1920x1080p, H.264, etc..), then burning that file as a "Data Disc" to Blue-Ray, then playing said mp4 in VLC on my PC. Any direct burn of this in the 2 "Blue-Ray" outputs result in a 10:1 file size reduction to m2ts that won't play anywhere!
My guess is that there are scores of users out there who have authored multitudes of blue-ray discs from V-Pad with equipment and requirements like to mine, and I hope that several might chime in to what works consistently for them. Any and all replies are extremely welcome, and will be consistently checked until I can play a disc in my living room, and I won't fail to post when I'm there, THANKS!
