I am using a mz-m10. I have only recorded 4 sessions with it using the supplied mic. I am exporting to a mac so I am recording in PCM. Previous sessions worked great. Now, it won't record at all. I've checked all my settings and they appear to be correct. Battery is charged, Hi-MD is displayed, little balck square is there, PCM selected. I insert a blank disc, it displays the title screen which of course is empty. I hold the jog dial and press the record button and all it does is display "Blank Disc" and doesn't start recording. If I press the reocrd buttons again it displays "no track" Same issue occurs whether I am using a Hi-MD or MD 80 disc Any ideas???? Thanks Rick
