What hardware + XServer do you use?
- If it's not working due to MMX code, look for
Make it use rep_movsl() for copying instead of memcpy(). This code is also
optimized but without mmx. If dga still doesnt't work, you've got
other problems ...
vo_fsdga is not maintained by me and a VERY old branch of vo_dga forked
by arpi, I guess ...
