michiganjfrog,
i dont know exactly how to identify them but i know they dont come up as 0, i only have one file that is 0 and it wont play on my player.
The files that are VBR seem to have wierd kbps (which i only just checked and may be my problem) some of my file say they are 663 and 557 kbps and since the player dont usually play files with such a high bitrate this could be my problem maybe somone encoded them with max kbps at 663 or maybe windows just gives an incorrect bitrate for VBR (probably since it could only be an average and theres no way they average out at 663?) any way im sure some of ur files will be VBR look at the kbps while the song is playing on ur mp4 player and it will go up and down in real time, well it does on mine at least.
neway my firmware is 9.0.50.
i have heard SportaPros sound quite good, i really want to know aswell how they compare to ipods etc.. i have good sennheisers but no headphone amp or anything so i cant really test it on those

i guess i will have to wait and see on super-fi's and hope for the best :lol:
