* Finally fix FS#11476 (data abort when playing some sv8 mpc files on lowmem ↵Andree Buschmann2010-10-02

When playing sv8 files this resulted in seek to filebegin, then fileend, then back to filebegin. Such seeking behaviour results in heavy rebuffering when playing files on targets with low RAM. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28197 a1c6a512-1295-4272-9138-f99709370657
