Worked before version 4

So I was running version 3 of ConvertXToDVD and all was good with the world. Now I’m using version 4 and the troubles begin. I can go through the whole convert process and see the image on the screen but when it comes to burning the DVD I get " no disc in drive". This is very weird, because the log file seems to recognize the drive through the converting process, but loses it when it comes time to burn the file. I’m using -r discs and nothing fancy here. DVD is a Samsung 8x slim external plug and play writer.

Moved from Samsung writers since this is a problem with ConvertXtoDVD, not with the drive.
