Problem on music streaming

Hi,

I am using my DS212J (with DSM 4.1) as a streaming server to provide music files to my Rotel RT-12 Hi-Fi converter.The problem I have is that the stream is interrupted on some of the tracks for some reason I don't understand. I am using a CPT network (actually, I was doing it in wifi and had the same problem and I bought a CPT equipment to avoid these interruptions...), shouldn't come from there. When I read the same track with DS Audio on my Android tablet in wifi there is no problem at all.

The only thing I can see is that tracks on which I have problems were converted to FLAC from my CD collection. When I read FLAC files purchased on the net, there is no problem.

So, I am a bit confused. Have you heard of any problem related to the streaming algorythm ?

Any help will be apprecited.

I didn't find the right solution from the Internet.
