[MPlayer-users] Can't "-vf scale=xxx" in mencoder

Tue Sep 26 17:13:12 CEST 2006

Thanks.  Actually I'm using gcc 3.3.4, but I take it
I'll need something more like 3.4.x.

I'll have to figure out whether I want to fix this or
not because it's a mythbox running SuSE 9.2 and I've
never upgraded a distro's gcc outside of its standard
packages.

Eh well.
