I have my DV29 connected to a current-generation Pioneer plasma (PRO-1120HD) by an HDMI cable. I have no separate audio connection between them. My problem is that when playing a cd or dvd-a on the DV29, if I then turn on the plasma and it was last on the DV29 input for the display, or if I have the plasma on but switch to that input, the DV29 will stop playing or even lock up causing me to restart the DV29. I don't recall if this happens every time, and I have not done scientific checks to see when it does and doesn't occur. But it did again last night when I turned on the plasma with a cd playing. Is there an incompatibility here? Is there some kind of signal sent back to the DV29 when the display comes on to the DV29 input? Other than "just don't do turn it on when it is playing," any thoughts, setting changes, or other ideas would be greatly appreciated. I plan to write Arcam support also. Thanks in advance.
