This seems to be a vidcap bug
When, in vidcap, I switch from the current tape to another tape, I get a message:
"There is no disk in the drive. Please insert a disk into drive e:"
Cancel/Retry/Fail
All of the buttons just cause the message to repeat. There is no way to gracefully exit vidcap except by killing it.
As it turns out, E: is a CDROM drive. Putting a CD in the drive solves the problem.
I have no idea why vidcap needs me to have a disc in there. I've never stored any media there so none of the files in vidcap should have paths pointing there.
