Here's something interesting... it's been over 4 hours and now all videos have stopped playing. No video previews for each game and no videos for the platforms. It's just black. But it's not locked up. I can still navigate through the menus. I'm using the Unified Refried theme, and I'm still using WMP for the video player.
Good question. I remember changing it in LaunchBox, but honestly, I can't remember if I shutdown LaunchBox first, or started BigBox from the LaunchBox menu. I'll give your suggestion a try.
Mine freezes up within 30 minutes booting directly into attract mode. I tried changing to Windows media player but still the same issue. I rolled back to 13.18 and so far no issues.
