pontosan mi bajod van ezzel? Nálam pont így működik.

~/bin/cropconvertvcd: (Meghívod "cropconvertvcd fájlnév X:Y"-vel, ahol X
és Y a méret, amibe át akarod méretezni. A cropot interaktívan
beállíthatod. Ha a hangot konvertálni akarod, lejjebb kommentáld ki a
második oacopts= sort.)

A good engineer will make considerable effort to avoid additional effort.
