I personally do not buy them, because it is not very good brand...:Z
But I had a 10pcs. cake and burned all without problems (411@811, HS0K) - they play in my standalone from the start to the very end.
But as I said, it's not a good brand, so You might had got some crappy batch of them - PRINCO is very "well" known for their varying quality. One can be perfect a the other kinda shi**y:confused:
I don't think it is the burner, that causes problems...
