I'm well aware that AVL already has multiple video transcoding tools such as Avidemux and WinFF but, not only can I never seem to have enough of the darn things, AVL seems to currently lack a general purpose GUI for mencoder (the only real rival/alternative to ffmpeg that we have) and the best example of such an app that I know is available for Linux has to be Lincoder:
http://lincoder.sourceforge.net/Any reason it didn't make it onto 5.0.3 GMaq because I'm sure you're aware of Lincoder's existence and its usefulness to us types?
