in/ on Quicktime. I hope this is the right place to ask. We have surveillance cameras (critter cams, actually) that record in .avi format. The original application recommended by the camera manufacturer (Foscam) was VLC, but it went haywire this week, so I called Apple Support to see if there was an app that would play it. I ended up with Elmedia. I was initially all happy because now I had actual video, but on hour 2, it apparently got stuck on one particular file and keeps playing that one over and over. Can anyone suggest an app that will play .avi files? I don't mind paying for it if it will just work and be reliable.
