Just downloaded latest avidemux.
Noticed there is a setting missing in output, used to have 2 settings for mp4- mp4V2 and mp4

Never did figure out what the difference is , but now just mp4 showing. So my guess is they just use best version and done away with V2?

But one thing was annoying, I used to open vid files from Windows context menu by right clicking "open with" which brought up options like VLC, MediaInfo, etc and it used to have context menu for opening with avidemux,which was convenient.
But now avidemux is missing in Win context menu.

Anyone know how to get it back?
