I wouldn’t worry about it.

Hello. Not sure if your microwave is a Maytag or Samsung, but it seems like here is a video that may solve your problem or at least explain it: https://www.youtube.com/watch?v=_yWSU0kT... Seems like a lot is involved, if you or someone you know is handy, it may be an easy fix.

Not sure if you're still interested but you can use a program called "CyberDuck" (https://cyberduck.io/) to access the contents of the AppleTV (1st Gen) hard drive. You can transfer media back and forth and make additional changes as well. There are also various third party programs such as those by FireCore and OSMC that will allow you to stream content and view a wide variety of media (flv, mp4, mov, avi etc) on your ATV1. I am currently using OSMC on my ATV1 using the linux based OSMC Kodi Krypton for my viewing needs. Keep in mind it will alter your ATV1 but you are able to reinstall the original OSX if you desire. Wouldn't hurt to check it out. I recommend OSMC. Google.
