Slow playback in Maemo 4 Diablo

[bl8086]

Hello! Sorry to ask this question, but I looked for a solution in many sites (also on maemo.org) and I have not found any solution. I'm using the version of RockBox for Maemo 4 Diablo (maemo.org specifies only the version for Maemo 5). Deb package installation runs normal in N800...

The RockBox opens normally, but music playback is slow for all codecs.

It says that the port is playing normal using gstreamer: http://www.rockbox.org/wiki/MaemoPort

My system is installed on the memory card, but I dont know if this could affect the performance of it...

Sorry for the mistakes, I'm using a translator. Thanks! =D
