i have problems with linux software (of video kind; using mplayer). These are as follows:
1. It runs on different hardware using Fedora 6 to Fedora 8
On a hardware which has Fedora 9 (cannot install anything less) it hangs
2. Even on this problematic hardware, or OS, it works when running manually. However, when running from a startup script it hangs
3. While debugging i noticed that sometimes it hangs in the middle of open system call, trying to open a fifo file. On other occasions it hangs while executing pthread_create( ). Again, when running manually those operations are successful.

Looking for ideas on how to crack this situation...
