Metadata problem when transconding a relay

[radiopirata]

Hi all,

I'm quite new to this forum, sorry if I'm posting in the wrong place.
I've been searching a bit before to post and I didn't really find a solution to my problem, so maybe some of you can help me.

The scenario is a main server with an HQ stream and a server with a LQ stream.
In order to avoid bandwidth problems I though to generate the LQ stream by transcoding the High Quality one directly on the server.
I've tried many different configurations and versions of DNAS (1.9.8 and 2.0) but nothing changes.
The upload stream originated from my PC in AAC+ 96kb goes to HQ Server (right now 1.9.8), then sc_trans is configured to relay the stream, convert it to MP3 96kb and sends it to server2 (right now DNAS 2.0). Transcoder is TRANSCast/posix(linux x64) v2.0.0.54.
OS: Linux Opensuse.
The audio is ok, the metadatas are ok ONLY on the first server... and i can't really figure out how to fix them:

Example:
server 1 (HQ): CHICANE - SALTWATER
server 2 (LQ): CHICANE%20%2D%20SALTWATER


Please, can somebody point me in the right direction?

thanks A LOT in advance.
Flavio
