The bad news is that it's so bad I'm surprised it plays at all :(.
1/ Is this media really branded Verbatim?
2/ Do you have any other media - maybe a 4x DVD+RW?
3/ Do you have a lens cleaning disc?
The first thing I would suggest is to use the [thread=112103]EEPROM Utility v3[/thread] to do a reset learn. Use the utility to backup your EEPROM first and then use the Reset learn function. Make sure you select the correct drive from the drop down list at the top. After this, burn another disc preferably a DVD+RW so it doesn't waste a disc. Post back with the results...
