Dear Tom,
unfortunately the update GameEx install is also not working. I use the latest LAV codecs on my system, and everything worked fine before your latest update. I got all the media files on a harddisk from a fried, so I do not know the source or the capturing parameters exactly. I have a Sega Naomi cabinet with with Sanwa 29E31S (I guess multisnyc) monitor. The videos are running, if I install a player (e.g. X-Codec pack). I have attached two videos from my mae folder. The mame games are running fine (emulator setting still OK). I had problems with the key setting to control the main menu. All settings were as before, but the buttons and the second joystick did not work. The first joysitck is also installed as "Joystick" instead of key mapping. This worked!
Edit: I tried "Windows Media Player" here I find the same issue with the videos: sound yes, video no. But X-Codec player is working fine. Maybe the video format is outdated?
Another solution is, that you give me GameEx 2.50, that worked like a charm. Unfortunately, I have deleted the setup.
Thanks for your help!
Torsten
