I'm trying to "Prepare", not "Burn" a bluray video, 1920 x 1080, it's about 10 minutes long. I've done this type of projects for a few years now, this is the first time I've encountered this problem. The error mesage :

File name: 00001.m2ts
Status: Vegmuxtw.dll::CTSWrapper::ProcThreadMain::Video buffer underflows.

Please help me understand what it means, and how do I solve it? I've restarted the PC and DVDA several times.

Thank you!
