hi,

i went through the trouble and made the dfbmga mode work in freevo and mplayer yesterday on my g400 and thought that it might be worth to share my results with you.
first of all, it really involves a *lot* of work as it involves compiling a patched kernel and recompiling mplayer with a patch. it is definately nothing for linux newbies. categorizing myself as relatively experienced on unix, i needed almost half a day to make it work properly (although i spend most of the time debugging a really really stupid mistake).


why did i even bother? ever since i used the g400 tv-out on linux i had diagonal (rgb) lines going through the picture which basically brightend up the picture where these lines were (using mga_vid). i almost got used to it, but it's definately is annoying. the good news is: using dfbmga, these lines are gone and i would even go on and say that the picture quality is more sharp than with mga_vid. others don't experience this enhancement though (thanks to rshortt for helping me a little).
then, using the old mga_vid method, i sometimes experienced framebuffer lockups when i had to quit freevo using kill (sometimes my remote control just doesn't react anymore. i haven't found the source of this problem yet). i had to restart the computer when i had this. these lockups are gone too.


however, one thing i couldn't correct yet is that my self-compiled mplayer would somewhow fall into an endless loop when trying to play ogm files. i guess i'll just have to compile it one more time and check everything more carefully or so...

so if you are having trouble with mga_vid, i'd definately recommend giving directfb a shot. you just need to be aware that you may need time to make it work.
