anyboy help with this? i selected sync music and un checked all other categories (Movies, TV shows, etc). The first time i left it overnight synicng via ethernet cable. in the morning it had finished, but i noticed only 3,500 songs (80Gb/lossless) of the entire library of 10,000 (203Gb/lossless) had been synced. i knew that i wasn't going to get all my music on the ATV as the internal HD is only 160Gb, but shouldn't it be snycing a lot more than a third of the library? streaming works fine with entire library. just wanted to fill the HD with music so i didn't have to have iTunes running to listen to tunes. i'd appreciate any tips on what i might be doing wrong.
