Third generation players seem to have the most problems in this regard. Updating to firmware 4.0 helps in many cases. Generation Two players seem to be the most reliable. The first generation players work well until the NEC drive fails. Overall, I prefer Generation Two and Generation One to Generation Three players, although my A30 is great most of the time, especially after the 4.0 upgrade which seemed to solve the problem of quitting halfway through. Just my HO.
