I found  FS#8521 (permanent pitch setting) can successfully combined with mpeg player.
Add  FS#8521  and some fix, we can use pitch function in mpeg player. This means, we can control mpeg play speed.

With  FS#8894 (speed control without pitch change) can produce similar effect and more attractive, but  FS#8894  have serious problem with gigabeat s30 and require more processer power and have lower sound quality.

This patch can patched with  FS#8607 (mpegplayer playlist).
