Thanks morenu
OT:
I think Rockbox is really cool. It has nice features like the database where I can choose tracks by ratings and so on and it's very fast. The Audioscrobbler.log rocks too
But I'm a little disappointed from the Rockbox team. Together with Miika Pekkarinen (responsible for Rockbox database) I found a bug on the file system level for the Sansas which is why data is'n stored correctly on the sansa (Bytes are missing or added within files). But they don't seem to be interested in that. I posted it on the forum but all they did was closing the topic and deleting it. That's not the way I used to know from support-forums, especially if I compare it with the Mediamonkey forum

. So I let it go and will have a look at it in a few month.
BTW That file system bug is the reason why the Rockbox Database might not be read correctly. I've tried to handle all possibilities, but that's not 100% save.
Nevertheless Rockbox has a long way to go.
USB Support is still missing and the handling isn't easy if you don't really know what is done in background.
It took me 4 days to get everything I want.
The choice isn't easy.
Using the original firmware whith nearly no features and sometime strange behavior (Rating takes up to 4 Minutes

) or using Rockbox with a lot of features but knowing that it's very buggy at the moment.
