Also, make sure that the 568 is set to controller (not auto) and everything else is set to non-con (not auto). Then do as Steve suggests.
Presume that you have checked the "800 present" on the pc config?
Occassional no sound on start up is a bug. Others have found this also. I haven't had chance to report it back to HQ yet though. Anyone else done this ?
Drop out is also a concern. I haven't experienced it on DVD-A, but, as mentioned in a previous post, I do get it very occassionally on CD playback. I have no idea whther this is player or SSP related. I do know that it p's me off.
