Query: burn speed not as represented

Every disc on this spindle burned at a maximum speed of 4X. This was the case on two different burners made by two different manufacturers, one of which was a TDK burner. It was also true using different software burning programs. I've never experienced this problem with any other DVD after many years of using many different brands, including TDK. If you're looking for a 4X disc, these are probably fine. I had no problems burning at low speeds, but the packaging and product descriptions were, for me, inexplicably inaccurate and frustrating.
