End of my own silly thread. Maybe useful to someone for reference, who knows. Silly Problem nº 1: always make sure that your unit is connected to the mains and that polarity is correct. According to experience Sony units can take wrong polarities for an incredible amount of time, but it can seriously damage the unit. Silly problem nº 2: In case there are what seem to be transfer problem, it is useful to see whether the problem is the actual transfer or the previous conversion to ATRAC. This can easily be done by converting before transfer. It can also be easily seen if the problem is with any format or, perhaps, just mp3. In the latter case, one cause can be ffdshow. Go to Programs, ffdshow, audio fileter configuartion and disable the MP3 filter. Conclusion nº1: don't post before making sure that you can fix the problem just by doing some search on the forums. Conclusion nº 2: don't post in the wrong forum. This is really a software problem.
