Many years ago my BAT VK-D5 player would not read some commercial compact disks but was able to read other disks okay. There was nothing I could do to fix it so I contacted BAT. Unfortunately, I was told my transport mechanism was not working and my BAT VK-D5 player was out of warranty. I returned the player to BAT for a new transport and they also installed new tubes.
When the unit was being repaired at BAT, I did some research and discover that others were also having similar problems with the BAT transport. The player worked fine when it was returned but I decided to sell it. I informed the new buyer of the new transport and reduced the price for a quick sale.
I do not know why your player will not read certain disks so I suggest you contact BAT for assistance. Will another player play your older or burned disks okay? If not, then the problem is with the disks and not the BAT player.
