Yeah, um, thanks,
I know I don't NEED a burner in my DVD player but they are uber cheap these days and I thought the additional buffer (8MB vs 236kb on other drives) may make the layer change seemless. I'm one of the lucky ones for which the original DVD drive in my Momitsu has always worked perfectly. However, the layer change is still notice-able.
(Not nearly as bad as the layer change on my Sony DVD player but still notice-able.)
