Even with the latest firmware in my Pioneer 105 the Verbatim 8x discs
sometimes cannot be recognized in my LG-3510 player. There is no problem with the JVC player. The LG has no problem with the 4X discs.
So I bought a bunch of 4X's from ProVantage and I guess I will try a new faster burner. This is with DVD-A2.
