Copies play on computer but not on karaoke machine

[kaptain]

I'm using Sony blanks which might be the problem. What I couldn't understand is why the copies would play on my computer or a more expensive player. Some of the earlier copies would and still will play on the cheaper player but the newer ones will not. I did find out however that if I slow down the write rate the copies I make will still play on the cheaper machine. I would, of course, prefer to write at the faster rate but only if it will play on everything.

thanks for the help
