Some CD players are more sensitive to the recording speed than others. Occasionally mine refuses to display folder & track data on CDs that have previously been fine, then later they'll work fine again. Maybe it could be something to do with temperature affecting components?
Don't forget to put your 1st album's worth of tracks in the root folder... just makes my OCD chill out a bit to see the 1st album on a disk show as folder 1 instead of folder 2...
