Hi Eric I think this might fix the issue, this is a recurring issue, not now in VP17. Assuming you have another version of VP that IS working ok, just change the VP numbers accordingly. Found on the Magix VP forum …
“This was Oldsmokes solution” …
“Here is a little bit more. If you have VP14, rename the folder C:\Program Files\VEGAS\VEGAS Pro 15.0\bdmux to something like bdmux-vp15. Copy the same folder from VP14 over to VP15.”
