VLS stream too fast!!!!!

Hi:
I use VLS to stream a mpeg2 TS, and use unicast. (streaming to my embedded device)

And in my embedded device(64M RAM, file system is RAMDISK), has two process, one is VLC, it receive the UDP packet and redirect the package to a "pipe", another is a player(provider by sigma), the player read the "pipe".

Two question:
1. Since VLS stream is too fast, about 20s, VLC process will be terminated by OS, because it buffer fulled. How can I control the speed rate of VLS streaming?

2. The player playback stream, not smootly, about 10 fps. Why?

PS: the bridge from VLC to "3rd player" is a "pipe", made by "mkfifo".
