recently I can record 5 Or 6 albums with no problems on playback the first song of an album will play about one minute fine and then skip through the rest of the song with a weird noise. Anyone know why this would happen? sometimes I can succesfully re-record the song and sometimes it does the same thing. I have no idea if its the md player or the software or the media. The cd is fine and it is not from copy protected Cd's.
