Hi People,

I've got a nice effect: playing a divx5 file (episode 2 trailer)
causes mplayer to open mga_vid twice:

---schnipp---
$ grep open /tmp/strace.out | grep mga
open("/dev/mga_vid", O_RDWR|O_LARGEFILE) = 6
open("/dev/mga_vid", O_RDWR|O_LARGEFILE) = -1 EBUSY (Device or resource busy)
write(1, "Couldn\'t open /dev/mga_vid\nUsing"..., 167) = 167
---schnapp---

here the ouput of mplayer -v:
---schnipp---
$ mplayer -vo xmga ep2_clone_war_p640.avi  -v
