I converted a bunch of songs, that are CBR at 128Kbps and 144Kbps to ATRAC3 / 66Kbps like I always do for a longer playing time, some songs will play fine, but 99% of them will sound like they are playing at double speed. I used to transfer my songs from Mp3 to my Sony MZ-N510 player using Sonicstage 2.1 but suddenly it stopped being able to convert ANY of my songs and said "SonicStage does not support the file format" I downloaded SS3.1, and he was again able to convert and transfer the songs, but many are playing at double speed. What can I do ? My PC is a Windows 2000, Pentium 4, 2.8Ghz, 1GB RAM I am using SonicStage 3.1
