I haven't used Easy VHS to DVD for a while, but it hasn't been all that long. I definitely used it with OSX Sierra - though it is possible I haven't yet tried it with High Sierra 10.13.5 until today. The hardware setup is exactly the same, so it has to be some type of software issue. I'm wondering if it has anything to do with the 32-bit vs. 64-bit warning I get when I launched Easy VHS and Toast, explaining that the developer needs to optimize the app for the new 64-bit environment. I'm assuming this isn't something that could cause the problem I'm experiencing, but I feel like I've ruled everything else out. I've updated both apps to the latest versions I could find (though I'm still not entirely sure what role Toast 9 Basic has to play, but all of the responses to similar issues seem to recommend updating both applications.
Anyone been able to confirm that Apple's latest OS is in fact the problem? This wouldn't surprise me all that much, as this is without question the worst OS I've ever seen from Apple in 25 years of buying their computers. It seems to be part of a troubling trend - iOS11 was a nightmare as well, and I actually just had to send my brand new Macbook Pro in for repair to have the entire logic board replaced after experiencing a number of simultaneous hardware failures.
Any guidance appreciated - I just got my hands on a VHS copy of some old home video that was originally recorded on 8mm and am anxious to share it with my family.
