Well, it isn't real PAL your outputting. The best computer resolution equivalent to PAL resolution is 720*576 (Tv's have non square pixels). On the other hand, your TV would definatly trash a non-interlaced, non PAL signal . So your g200 video encoder actually handles the conversion, and this is a bit of a black-box procedure. When u see interlacing artifacts (tearing and such) it's probably because your interlaced source isn't played back with the fields in the correct order i think. PC's normally don't care much about interlacing, and even less about things as fields. PC's are in a frame world, TV's in a field world. So u have 2 option : directfb+dfbmga, wich can display video in a correct field order, but i don't know if the directfb drivers work on a G200 Marvel. The second option is deinterlacing your video completly (u can set that option in the freevo menu, but i noticed it doesn't always work on dvd's. The mplayer man page says u should use -vop lb=0x20000 for interlaced dvd's, wich does work correctly) . So when your video is progressive again, your matrox video encoder chip will do it's job and interlace the fields right when transmitting to the TV, in the correct field order. I hope this explains things a bit (and that i didn't put to much crap in my explanation) Mvg den_RDC ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Freevo-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/freevo-users
