Well with a little more digging I have found that it maybe CPU Related,
compiled the 1.6.1.93 on my fileserver which is a AMD K6-3 450 and
everything works fine when using mpeg2enc and the
#define HAVE_POSIX_MEMALIGN 1 is set But with the Same OS Version with my
Athlon Slot-A Tbird it will not work.
My other System Is a Slot A Athlon also but it is a Classic and does not
have the Same Version of the OS, But it also seems to work fine.
I will be upgrading to a Athlon XP 2400+ Maybe today, Will see what
happens then with the Current OS SuSE 7.3.
