i’m using svn r29659
when changing spc songs frequently in file browser, the spc codec freeze the whole system, the displace shows “loading”.
i’ve done some further research:
1.change songs in the playlist have no problem.
2.tune on the database can reduce the freeze possibility.
3.tune off the dircache can slove the problem, but it makes the file browser moves very slow when doing some heavt jobs.
