Though some do tend to work better than others in certain Burners and with certain programs (it's rare, but sometimes certain burning programs will not be able to write to a disc). Usually, it's that one disc's fault (sloppy manufacturing, low quality, cheap recording layer, etc. etc.) which in turn is the manufacturers fault 'cause they tried to get too cheap with making them.

That... and it's an interesting poll.

Oh... and it's just for fun!
